Umbhali kwengcamango ubume oganikhi khompawundi. Imfundiso ubume oganikhi khompawundi A. M. Butlerova

Chemistry - isayensi ukuba usinika onke ezahlukeneyo izinto kunye nezinto zendlu, apho akazange athandabuze ukuba sisebenzise yonke imihla. Kodwa ukuba beze yokuvulwa wawuneentlobo iikhompawundi, nto leyo eyaziwa namhlanje, ekhemisi abaninzi kwafuneka ukuba aye ngokusebenzisa indlela kwesayensi.

A omninzi, imifuniselo ezininzi ezibe yimpumelelo yaye aziphumelelanga, ezinkulu senkolelo isiseko solwazi - konke oku kwakhokelela ekubeni ukuyilwa kwiindawo ezahlukeneyo of chemistry kwimizi eye wavumela ukuba nokulungelelanisa nokusebenzisa izinto mihla: irabha, iplastiki, iiplastiki, nentlaka, aluminiyamu, iiglasi ezahlukeneyo, silicones, njalo-njalo.

Omnye, ekhemisi edumileyo imbeko, lowo wenza igalelo elikhulu kuphuhliso organic chemistry kwaba bantu Russian Butlerov AM imisebenzi yakhe, impumelelo kunye neziphumo umsebenzi gqabagqaba kweli nqaku.

curriculum vitae

Umhla wokuzalwa sisazinzulu - ngoSeptemba 1828, inani kwimithombo eyahlukeneyo ayikho iyunifomu. Yena unyana uLieutenant Colonel Michael Butlerova unina kwakude kudala ngokwaneleyo. Zonke ebuntwaneni wahlala phezu estate usapho utatomkhulu wakhe kwilali Podlesnaya Shentala (ngoku Republic of kummandla Tatarstan).

Wafunda kwiindawo ezahlukeneyo, okokuqala kwisikolo sabucala evaliweyo, ngoko kwisikolo samabanga aphakamileyo. Kamva, wayengena University of Kazan kwisebe ye physics nakwimathematika. Noko ke, nangona oku kakhulu abanomdla chemistry. Umbhali elizayo thiyori ubume oganikhi khompawundi ahlale emva kokuphumelela endaweni njengomfundisi.

1851 - ukhuselo ithisisi yokuqala kwizifundo kwi "oksijini ze -oganikhi khompawundi". Emva komsebenzi qwa wanikwa ithuba lokuba ukulawula yonke ukwakheka eyunivesithi.

Umbhali kwengcamango ubume oganikhi khompawundi ibe ileli umsebenzi elide yaye ngo-1874 waba ngomnye buchopho best St Petersburg Academy of Sciences.

Scientist wafa ngo-1886, apho wachitha ebuntwaneni kwilifa usapho utatomkhulu wakhe. Xa intsapho indlu yenkonzo zasekuhlaleni waza wangcwatywa.

igalelo Scientist ngayo kuphuhliso lolwazi chemical

Imfundiso ubume oganikhi khompawundi Butlerov - kodwa ngokuqinisekileyo msebenzi wakhe uphambili. Noko ke, akukho enye kuphela. Yaba lo nzulu kudale sisikolo sokuqala Russian of ekhemisi.

Yaye neendonga zaso oosonzululwazi ezinjalo, owathi kamva waba ubunzima enkulu kuphuhliso lwe lonke yenzululwazi. Aba bantu balandelayo:

• Markovnikov;
• imivundla;
• Kondakov;
• yaseTabhore;
• konovalov;
• Lions nabanye.

Umbhali kwengcamango ubume oganikhi khompawundi sele kudale imisebenzi kwi zenzululwazi zendalo, kuquka chemistry. Ingakumbi uphando oluninzi luye yokusingelwa phantsi kuyo oganikhi khompawundi.

Umsebenzi organic chemistry

imisebenzi enjalo kubizwa lukhulu. Emva Butlerof phantse lonke ixesha free wachitha kwilebhu yakhe eyunivesithi, ekwenzeni imifuniselo eyahlukeneyo, ngokwenza iziphumo kunye nezigqibo. Nje ngoko ke wazalwa imfundiso lwesakhiwo chemical oganikhi khompawundi.

Kukho ezinye umsebenzi ingakumbi ngqongqo Scientist:

• luqulunqwe yi kwingxelo inkomfa kumxholo othi "Kwi isakhiwo eekhemikhali nto";
• umsebenzi imiqingo "Ngomhla oli kubalulekile ';
• Umsebenzi wokuqala yesayensi "Le igcwala ye-oganikhi khompawundi".

Ngaphambi kokuba amagama ayo kunye nokudalwa umbhali kwengcamango isakhiwo iikhompawundi organic ixesha elide ukufunda umsebenzi kwamanye izazinzulu abavela kumazwe ahlukeneyo, ndandifunda imisebenzi yabo, kuquka umqhubi. Kuphela ke, ukuba iimeko kunye nokumisa ulwazi olufundiweyo, wayebonisa zonke izigqibo ngokubhekiselele theory baso besiqhelo.

Imfundiso ubume oganikhi khompawundi A. M. Butlerova

ngekhulu XIX kuphawulwa luphuhliso olukhawulezayo phantse zonke Sciences, kuquka chemistry. Ngokukodwa, qhubeka ukuba ukuqokelela izinto ezifunyaniswe ezininzi carbon kunye nemixube zalo, nezinto eziphilayo kuchaphazela yonke ngokwahlukahlukana kwayo. Kodwa akukho bani onobuganga ukuhlela amalungiselelo zonke izinto eziyinyaniso, kukhokelela ekubeni zifana kwaye qwalasela iiphatheni eziqhelekileyo, apho yonke into yakhiwe.

Eyokuqala yenziwe Butlerov A. M. sithe ingcamango okhanyayo ngesakhiwo eekhemikhali oganikhi khompawundi, amalungiselelo apho wathi ubunzima kwinkomfa waseJamani of ekhemisi. Esi sisiqalo sexesha elitsha kuphuhliso inzululwazi, chemistry ephilayo laqalisa kwindlela yophuhliso esebenzisa amandla.

Le Isazinzulu waya kuwo ngcembe. Wachitha ixesha elininzi uhlolisiso nezinto kwangaphambili ubukho izinto ngempahla kwangaphambili, wafumanisa iintlobo ezithile reactions, waza wabona emva kwabo ngekamva. Abaninzi bafunda imisebenzi oogxa babo bakufumeneyo. Kuphela kwalo msebenzi ngenyameko yaye onzima ekusafuneka wakwazi ukwakha wobugcisa yakhe. Kwaye ngoku, ingcamango ubume oganikhi khompawundi kweli candelo Chemistry - phantse iyafana naleyo inkqubo ngamaxesha athile ezingaphiliyo.

Ukuvula sisazinzulu ngaphambi kokudalwa theory

Ziziphi izinto eziye zenziwa kwaye banikwa sisizathu umphengululi phambi kokuba kubekho ingcamango ubume be-oganikhi khompawundi A. M. Butlerova?

1. genius Domestic kuqala kuhlelwe izinto zendalo ezifana methenamine, formaldehyde, iodide methylene kunye nabanye.
2. Kuhlelwe sugar-ezingaphiliyo eziphathekayo (utywala ephakamileyo), ngaloo ndlela ebangela kuvuthelwa ecaleni ithiyori vitalism.
3. Yena kwangaphambili ikamva reactions polymerization, bezibiza ngokuba oyena zithembisa.
4. Isomerism kwachazwa kuqala kubo kuphela.

Kakade ke, olu kuphela abambe ngayo umsebenzi wakhe. Enyanisweni, iminyaka emininzi yomsebenzi onzima linokuchazwa yi zezenzululwazi ixesha elide. Noko ke, eyona okubalulekileyo namhlanje kuye lonke ingcamango efanayo ubume oganikhi khompawundi, leyo izikhundla uthethe ngakumbi.

Kwindawo yokuqala e-worldwork theory

Ngowe-1861, i-nzulu Russian omkhulu kwinkongolo ye ekhemisi kwisixeko yaseSpeyer ukwabelana noogxa iimbono zabo isakhiwo ngoonobangela kunye neyantlukwano oganikhi khompawundi, evakalisa konke oku ngokohlobo le ngcamango.

Na into yokuqala ethe kulandelayo: zonke atom phakathi zinemoletyhule oxhulumene ngokulandelelana, oko kuxhomekeke valency zabo. Xa le carbon atom imiboniso Isalathisi Valence esilingana ezine. Ioksijini unalo ixabiso zesi salathisi ilingana no ezimbini, hydrogen - ubunye.

Uphakamise inkalo efanayo ebizwa khemikhali isakhiwo kweziyobisi. Kamva ityumbe zakhe bathathwa ephepheni kunye neefomula graphic ngokupheleleyo lwezakhiwo, incitshisiwe ezinto.

Oku kwakhona lo mkhuba amasuntswana carbon uqhagamshele enye kwenye kwi- kwikhonkco engapheliyo lwesakhiwo ezahlukeneyo (linear, elibujikele, branched).

Ngokubanzi, ingcamango ubume iikhompawundi organic Butlerova indawo yayo yokuqala ichazwe ukubaluleka valency kunye nefomula yomanyano ezimbaxa nganye, iimpawu ezibonakalisa nokuziphatha iziyobisi ngexesha abasabela.

Imeko yesibini e-worldwork theory

Kweli nqanaba kwachazwa ukwahluka khompawundi eziphilayo ehlabathini. Ngokusekelwe ukudityaniswa carbons ezikwi, ISAZINZULU wacebisa ukuba kwihlabathi kukho iikhompawundi ezingafani ukuba iipropati ezahlukeneyo, kodwa lo kuqamba efana ngokupheleleyo eziphilayo. Ngamanye amazwi, kukho le ngxaki yokusetyenziswa isomerism.

Le mbono igatya ubume oganikhi khompawundi A. M. Butlerova wachaza kungekuphela nje undoqo isomers, kunye isomers, kodwa ke sisazinzulu ezibonakalayo ezifunyanwa kuqinisekiswa bonke.

Ngokomzekelo, yena kuhlanganiswa butane isomer - isobutane. Emva koko, pentane ke kwangaphambili ukuba zikhona akunakho kodwa emithathu isomers, ngokusekelwe isakhiwo ezimbaxa. Nokulungelelanisa kubo bonke, ebonakalalisa ukuba umsulwa.

Ukuxelwa indawo yesithathu

Kwinto elandelayo ingcamango ithi zonke athom kunye iimolekyuli ngaphakathi umchiza inye kuchaphazela iimpawu omnye komnye. Ukususela oko kuya kuxhomekeka ukuziphatha iyeza iintlobo ezahlukeneyo reactions, ebonakalaliswe yi chemical kunye nezinye iimpawu.

Ngenxa yoko, phantsi eli lungiselelo ukuchonga eziliqela iindidi khompawundi eziphilayo ezahlukeneyo imbonakalo nesakhiwo inkcazo iqela esebenza.

Imfundiso ubume oganikhi khompawundi A. M. Butlerova ishwankathelwe phantse zonke iincwadi organic chemistry. Ngapha koko, loo nto - ngenxa eli candelo, ingcaciso imithetho zonke, ezo zakhiwa molecule.

Ixabiso ukuba ingcamango lwangoku

Kakade ke, kubaluleke kakhulu. Le ngcamango wenza kube lula:

1. liwenze alungise yonke impahla oluyinyaniso elingathathwanga ngexesha indalo yayo;
2. chaza isakhiwo lweepateni, iimpawu khompawundi ezahlukeneyo;
3. ukuba ukunika ingcaciso epheleleyo yezizathu ezininzi ezahlukeneyo elikhulu ezihlelwe chemistry;
4. Wabanika eli lokuqala syntheses ezininzi kwezinto ezitsha, ezisekelwe phezu nezibonelelo theory;
5. bavunyelwa ukuba izimvo, ukuphuhlisa ingcamango atom-eziphilayo.

Ngoko ke, ukuba bathi ukuba umbhali kwengcamango ubume oganikhi khompawundi, ifoto apho ubona ngezantsi, wenza lukhulu - nto ayithethi nto. Butlerova zesini kuqwalaselwa uyise organic chemistry, umseki iziseko zayo theoretical component.

umbono wayo zenzululwazi zehlabathi, ubungqondi yokucinga, ubuchule phambili isiphumo wadlala indima ekuhambeni kwexesha. Le ndoda umthamo elikhulu ngenxa yomsebenzi, umonde kunye rhoqo, ukubuza synthesizing, baqeqeshwa. Engalunganga, kodwa nokusoloko ufunda izifundo kwaye wenze izigqibo ixesha elide ekunene.

Kuphela iseti ezinjalo iimpawu kunye nobuqili bezoshishino, ikhombisa ukuba ukufikelela neziphumo ebezifuneka.

Uphononongo of chemistry zomgquba esikolweni

Ekuhambeni wemfundo zamabanga izifundo organic iziseko anikwe ixesha hayi kangaka. ikota enye kuphela kwiBakala 9 kunye inqanaba kunyaka-10 (inkqubo Gabrielyan OS). Nangona kunjalo, ngeli xesha kwanele ukuba abantwana bakwazi ukuhlola zonke iiklasi eziphambili iikhompawundi, ingakumbi isakhiwo kunye nokuhlelwa, ukubaluleka practical.

Isiseko ekuqaleni kwekhosi - ingcamango ubume oganikhi khompawundi A. M. Butlerova. Grade 10 zanikezelwa ingqalelo ngokupheleleyo kwizikhundla zalo, yaye kamva - ingqinisekiso ithiyori kwaye iluncedo nasekufundweni iklasi nganye kwezinto.
