Formula ee benzene, kaas oo doorasho waa higaada saxda ah?

Consort leedahay beduliyum leeyihiin qaab xilliile ah. Wakiilka hore ee taxanahan ah - benzene (C ₆ H _6). formula A ka muuqato qaabka arrinta, marka hore la soo jeediyay farmashiyaha Kekule ee 1865. Sida laga soo xigtay sheekooyin of saynisyahan ah, wuxuu muddo dheer ayaa uga fikiray qarsoodiga benzene. Mid ka mid ah habeenkii uu lahaa Mas qaniina ay dabada u gaar ah. Subaxnimadii formula dhismaha ah benzene ayaa hore u la soo saaro. Waxay ahayd giraan ah ee 6 atamka carbon. Sadex ka mid ah ay ahaayeen at debaajiga double.

Dhismaha benzene

Carbon ee Consort leedahay beduliyum foomamka ah lixgeesle joogto ah. Mararka qaarkood marka lagu qoro falcelinta isleegyo muujinayaan ay elongated jihada toosan. Kooxdaan atamka leeyahay magac gaar ah - Giraanta benzene ah. Xaqiijinta ah ee qaab-dhismeedka xilliile ah benzene waa la helo saddex taagoo of alxamaad - hydrocarbon roodhida isagoo bond a xaafuun. Consort leedahay beduliyum sidoo kale roodhida iyo muujiyaan guryaha qaar ka mid ah caan ku alkenes. Sababtan awgeed, in giraanta benzene by saddex kusiga, barbar socda in ay wejigooda ku, la soco joogitaanka bond a double. formula benzene noocan oo kale ah ma si buuxda uma xusuusan gobolka atamka carbon in Britain ay.

Benzene: formula A ka turjumaya qaab dhismeedka dhabta ah

Sida xaqiiqda ah, xidhiidhka ka dhexeeya carbon in giraanta u dhigmaa midba midka kale. iyaga ka mid ah, waxa aan suurto gal ahayd in la qoondeeyo hal iyo double. feature noocan oo kale ah waxaa lagu sharaxay by dhismeedka electron ah benzene, kuna waari dhexdeeda xuduntii carbon waa in sp ² gobolka -gibridizovannom ku xiran wadamada deriska ee giraanta, iyo saddex hydrogen bonds hal caadiga ah. Xaaladdan oo kale geesle, oo ku yaal isla diyaarad 6 atamka carbon iyo 6 - hydrogen. Kaliya daruuraha electron afraad ee p-electrons aan ku lug hybridization ah, diyaarin si ka duwan. Waxa ay qaab eg dumbbell ah, xarunta uu hoos u dhaco diyaarad giraanta. qaybaha A awgii waa at sare iyo hoose. Xaaladdan oo kale, on xuduntii benzene iyo hoose waxaa jira laba degsiimooyin electron kulantay oo daruuraha ku electron p-isa. Waxaa jira dhigaalka kiimikada guud carbon ah ee giraanta.

Guryaha ee giraanta benzene ah

Sababo la xiriira wadarta cufnaanta electron u yaraynaysaa masaafada u dhexeysa carbon ee giraanta. Waxay yihiin sida 0,14 nm. Haddii in xuduntii benzene jirin bonds hal iyo double, waxa uu noqon lahaa laba koombo: 0,134 iyo 0,154 nm. Dhismaha dhabta ah ee formula benzene waa in aan ku jira bonds hal iyo double. Sidaa darteed, Consort udgoon loo gudbiyo xeryahooda organic roodhida rasmi ah oo kaliya. By Halabuurka waxay u eg alkenes, balse ay laga yaabaa in uu cadaanyo bedelay a, taas oo ah dabeecad u ah ee Consort cokan. xuduntii benzene leedahay beduliyum leeyahay xasiloonida badan si oxidants. Tilmaamo intaas oo dhammu waxay noo oggolaanaysaa in aan ka fiirsan giraanta nooc gaar ah ee isgaarsiinta - ma labo gool iyo hal ah.

Sida loo sawir formula benzene ah?

formula saxda ah waa benzene saddex bonds double sida in Kekule, laakiin qaab geesle leh goobo gudaha. Waxay astaan aqoonsiga caadi 6 electrons.

Waxaa la xaqiijiyay in ay qaab-dhismeedka dhabanada ee guryaha oo ah walaxda. giraanta benzene waa mid deggan, ayaa xigay tamarta muhiim ah. The guryaha wakiilka koowaad ee Consort leedahay beduliyum dhacaan homologues ay. Mid kasta oo ka mid ah loo soo bandhigi karo sidii derivative a kaas oo la bedelay hydrogen ku xag hydrocarbon kala duwan.
