Zinthu zazikulu ndi chiphunzitso cha Butlerova A. M. cha zinthu zazikulu ndi chiphunzitso cha mankhwala kapangidwe Butlerova

Konsekonse anazindikira kamba zofunika Butlerov chiphunzitso ankaona maziko zimapangidwira ano. Scientific koyamba makamaka zinthu kapangidwe. Iye anaphunzira mwatsatanetsatane chikhalidwe cha ubale wa maatomu.

Prerequisites chiphunzitso zikamera

Alexander Butlerov anali tate wa chiphunzitso chatsopano nthawi imene sayansi anasonkhanitsa kwambiri mafunso asayansi sanapeze mayankho. Mwachitsanzo, malongosoledwe a chodabwitsa anafuna valence ndi isomers. Komanso, akatswiri anapitiriza kutsutsana za mmene kulemba mitunduyi mankhwala. Butlerof Mukalongosola nkhani imeneyi. Iye anatsimikizira kuti njira zizionetsa kapangidwe ka nkhani.

Komanso, pali mfundo zingapo zimene zakhala adani zowonetseredwa ndi Butlerov. Icho chinali chiphunzitso kwakukulu. anayambitsa inali Jens Berzelius. Zimanenedwa kuti mamolekyulu ali zinthu zapadera - ankafuna kusintha zinthu mopitirira kuti chindipitirire zinthu wina ndi mzake. Panalinso chiphunzitso cha mitundu. amaukonda ankakhulupirira kuti mankhwala onse zovuta ndi ofanana nawo zinthu yosavuta zochita kupanga - .. Madzi, wa hydrogen, amoniya, etc. Izi lingaliro Zimatsutsanadi. Science anafunika chiphunzitso kuti kuika chirichonse mu malo ake.

Watsopano mfundo Butlerova

Dzina lake Aleksandr Mihaylovich Butlerov (1828-1886 gg.) Anali mmodzi wa akatswiri otchuka nthawi yake. Iye wachita mafunso ongolankhula wa sayansi awo. Mu 1858 wasayansi pa msonkhano wa Paris Chemical Society. Kwa nthawi yoyamba kuchokera mkamwa mwake adawomba chakudya chachikulu Butlerov chiphunzitso.

kafukufuku wagwiritsa ntchito mu lipoti lake kwa mawu atsopano, amene kenako anagwirizana mu sayansi lonse. Mwachitsanzo, anakhala wachilembo cha mfundo kapangidwe ka mankhwala. Asayansi akukhulupirira kuti dongosolo walola zinthu zosiyana perekani kuti gulu limodzi (makamaka, izi methane, chloroform, methyl mowa ndi zina zotero. D.).

Kufufuza kaphatikizidwe wa mankhwala

Mu 1861, mu Lipoti "Kapangidwe ka nkhani mankhwala" anali kukonza mfundo zoyambirira za chiphunzitso cha dongosolo mankhwala A. M. Butlerova. Scientific anafotokoza njira ya kaphatikizidwe ndi ntchito zosiyanasiyana zosiyanasiyana. Chimodzi mwa mfundozo chofunika kwambiri sayansi anali Satana ananena kuti aliyense chilinganizo mankhwala limafanana chimodzi. kufunika kwake kwagona amafotokoza kuti onse katundu ndi chimasonyeza ubale wa maatomu mkati mamolekyulu.

Butlerov chiphunzitso amatipatsanso kuti mothandizidwa ndi zochita ankalamulira zingabweretse zinthu zatsopano. Mu zaka wotsatira, ndi sayansi wotchuka ndi ophunzira ake anachita ya zatsopano kutsimikizira kopanda ichi. Iwo anakwanitsa lithe mankhwala atsopano monga isomers pentane, isobutylene ndi ena alcohols. Pakuti m'nthawi imeneyo, zinthu izi zinali kufunika yaikulu, amene angayerekezedwe yekha ndi kufunika zina zinthu zina za nthawi (mwachitsanzo, ekabora).

systematization zimapangidwira

M'zaka za m'ma XIX chakudya yaikulu ya chiphunzitso Butlerov a zasintha chifaniziro chiphunzitso cha kapangidwe ka zinthu mankhwala. Makamaka, wofufuza woyamba akufuna kuti mamolekyulu si mwachisawawa kudzikundikira maatomu. Tikawonetsetsa ali ndi dongosolo analamula. Maatomu umanena mnzake mu ndondomeko yeniyeni, amenenso amadalira chikhalidwe cha chuma lonse.

Butlerov, kukhala chiphunzitso chake, potengera mfundo masamu ndi malamulo. Ndi sayansi, iye anali kufotokoza kwambiri njira ndiponso zimene ankachita mu mankhwala. Kuti m'nthawi zinali kusintha kwenikweni. zoona zake n'zakuti ngakhale asayansi ndi kudziwa mfundo zokhudza zinthu zina, iwo sangamange nzeru zawo bwinobwino mwadongosolo. Kuweta chiphunzitso cha malo kapangidwe Butlerova anathetsa vutoli. Tsopano, umagwirira sanali olekanitsidwa Piggy banki mfundo ndi dongosolo coherent, komwe chirichonse umamumvera anasiyiratu mfundo masamu.

The zosiyanasiyana zinthu

The odziwika bwino chiphunzitso Butlerova zambiri zosonyeza isomerism - chodabwitsa ndi kukhalapo kwa isomers - ofanana kulemera maselo ndi atomiki zikuchokera zinthu zomwe nthawi yomweyo ali osiyana ndi mzake ndi kapangidwe ka makonzedwe a atomiki. Mbali ikufotokoza kusiyana kwa katundu wa nkhani m'chilengedwe.

Butlerof anatsimikizira chiphunzitso chake ndi chitsanzo cha byuteni. Malinga ndi lingaliro la sayansi m'chilengedwe ayenera kukhala mitundu iwiri ya nkhaniyi anali kumeneko. Komabe, pamene sayansi ankadziwa byuteni chimodzi chokha. Butlerof imachitika zatsopano zambiri ndipo akadali analandira chinthu chatsopano kuti ndi ofanana mu zikuchokera, koma osiyana katundu. Iye ankatchedwa isobutane.

Mmene maatomu pa wina ndi mnzake

Butlerov anapeza lamulo lina lofunika kwambiri. Ndi mapangidwe kumangidwa mankhwala elekitironi kusintha akuyamba ku atomu wina ndi mzake. Kumasintha osalimba. Kukhala elekitironi awiriawiri kuti bwanji latsopano chithunzi chuma ndi zinthu. Asayansi akhala akuphunzira zodabwitsazi pa chitsanzo cha mankhwala enaake a hydrogen, chlorine amene amasintha kachulukidwe elekitironi kumangidwa wa hydrogen.

Butlerov ndi ndizosowa chiphunzitso structural analephera kumufotokozera za kusintha nkhani. M'tsogolo, mfundo ya lotseguka Russian sayansi, anaphunzira mwatsatanetsatane ndi otsatira ake ndi ophunzila ake. Kudziwa zinthu kusintha njira walola asayansi kudziwa mmene lithe zinthu zatsopano. Yapadera ya mafunde a atulukira idayamba m'ma XIX. Ndiye European ndi American asayansi Laboratories latsopano pogwiritsa ntchito njira zimene zimaperekedwa Butlerov, akhoza kupanga zinthu zatsopano.

nsinga mankhwala

Butlerov ankakhulupirira kuti kapangidwe ka zipangizo akhoza kuphunzira ndi njira mankhwala. malo iri linatsimikizidwa zikomo ku mayesero ambiri bwino wasayansi lapansi. Komanso, wofufuza anali kutsatira za lingaliro lakuti njira angakhale olondola kokha ngati iwo kusonyeza kuti a nsinga mankhwala maatomu osiyanasiyana. Butlerov chinkhoswe mu kusanthula maganizo kwa zaka zambiri.

Iye kusiyana mitundu itatu limasonyeza - wosakwatiwa, pawiri ndi patatu. Wasayansi anali kulondola, koma pofuna kukwaniritsa sayansi yasonyeza kuti pali zinthu zina kumangigwa. Makamaka, akatswiri tsopano atha zimaonetsa iwo ngakhale mothandizidwa ndi magawo thupi.

Kukula ndi chiphunzitso cha Butlerov

Chiphunzitso chatsopano cha kapangidwe ka mankhwala mankhwala A. M. Butlerova chirengedwe chinali chuma. Wasayansi woyamba molimba mtima kuti mphamvu ofufuza kuphunzira katundu wa ma atomu, amene zinthu zonse zimamangidwa. Choncho Butlerof ankachitira maganizo akewo kuti nthawi. Iye ankakhulupirira kuti m'malo ayenera kukhala izo, chifukwa izo si angafotokoze mfundo zina zimapangidwira.

Wasayansi anali kulondola. Butlerov chiphunzitso anali anayamba kudwala mbali ziwiri. Chifukwa choyamba ndi sayansi wakhala kudziwa osati dongosolo la kugwirizana, komanso dongosolo okhudza malo maatomu mu molekyulu ndi. Kotero apo stereochemistry. chilangochi anayamba kufufuza mwatsatanetsatane dongosolo okhudza malo a mamolekyulu. Malangizo latsopano wanena kuti Butlerov, ngakhale pa moyo wake ndipo sanagone kuphunzira funso ongolankhula.

M'dera lachiwiri la sayansi chitukuko anali zikamera asayansi zoyenera kukonza pakompyuta maatomu. Sizoti ndi mankhwala komanso chilango thupi. Iwo anali ankafufuza mwatsatanetsatane akamanena za chikoka tonse maatomu ndi amachititsa zizindikiro anafotokoza katundu osiyana. Ndicho chakudya waukulu Butlerov ndi chiphunzitso asayansi amatha Mokhumbira amenewa.
