Pentane: isomers a me nomenclature

Ma mua o ka noonoo i ke kumu o haʻilula pentane isomers hōʻike i kēia hui no ia i papa no ke aloha 'ona. Eia kekahi, e hooholo i mall hiʻona i ka waiwai, ka mea i ka papa kuhikuhi kahua o ka palapala noi.

General ano

Pentane isomers a mākou noonoo e no i ka papa o ka paʻa kūhohonu loa (kali) hydrocarbons. Ka mea, i ka haʻilula CnH2n + 2, sp3 hybridization kalapona nā'ātoma, hookahi hoopaa. Mawaena o na waiwai ano no ka Poeikohoia o keia ano, a me pentane, isomers a hoi no i ka papa o alkanes kaʻawale'ano'ē hakahaka (halogenation).

Ke nomenclature o na hui

Ua nui kekahi mau 'hana e like me i kekahi ke haawi aku i ka inoa o kekahi paʻa kūhohonu loa hydrocarbons. Direct kalapona iwi ka loa pentane isomers i kapa hoʻohanohanoʻia kona mau'ano'ē (lala) mai ka papa kuhikuhiE kaula.

Mua, e pono e koho i ka loihi kalapona kaula. No ka helu ana o ka kalapona nā'ātoma o ka hapa i koho ia ma i i aia kokoke i ka luna radicals. Ma ke alo o ka lala ma na aoao elua o ka papa kuhikuhiE kaapuni i loko no o ka helu ana o radicals, e like me kā lākou 'ole (hoʻohana i ka Lūkini Hawaiʻi).

Inā he mea mau'ālike hydrocarbon radicals i loko o nā kiʻi hoike i ko lakou wahi me ka hoʻohana 'clarifying prefixes: di-, tri-, tetra.

Wale nō ma hope o nā mea a pau o ka hana (particles), e haawi mai i ka inoa o ke kalapona iwi kuamoo e e helu.

ka 'ole o ka pentane

Ua 'ano apau loa i ka papa kuhikuhiE mall haʻilula pentane isomers ka hoʻohana' ana i kaʻike mau algorithm. E hoʻomaka i hoʻonohonoho kalapona nā'ātoma i loko o ka hookahi kaulahao, loaa maʻamau pentane mall haʻilula: CH3- (CH2) 3-CH3.

Inā haʻalele i loko o ka papa kuhikuhiE pae o eha kalapona nā'ātoma a me ke koena e e hōʻike i loko o ka palapala o ka CH3'ano'ē. Ma ia ka hihia, ka mea hiki ke hana mau mall nā papakuhikuhi o ka 'ona pu ole, mai kekahi i kekahi hoʻoponoponoʻana o Kamehameha o meto pūʻulu: 2-methylbutane, 3-methylbutane.

Pehea'ē aʻe ke nana pentane? Nā isomers o ka haʻilula S5N12 i ke hooku iho la ia, a 2,2-dimetilpropanom.

Pau kēia mau mea halawai kekahi mau haʻilula CnH2n + 2, nolaila, e pili ana i ka papa o ka paʻa kūhohonu loa hydrocarbons (alkanes) e mall isomers.

Ke kŰia wehewehe i ke ola ana o ka isomerism hou i huiʻia me ka hoʻomaopopo like haʻilula, akā, like pu ole, i loko o ka hoʻoponoponoʻana o Kamehameha o nā'ātoma o ka lātoma. Mall isomers i kekahi oko ao ma ka reactivity, mamua o ka hookahi papa o hydrocarbons.

ka hopena

Pentane, isomers mākou no a ua manaoia, o ka typical Luna o paraffins. No keia papa o ke aloha 'ona i wehewehe aku e isomerism mau mea paa. Paʻa kūhohonu loa hydrocarbons mea ole interclass isomers. I waena o ka nui maoli o na hana ma ke koi pentane a me kona mall isomers, e koho i Nine Inch hana.

A hiki i ka isomerization o pentane, 2-methylbutane, i nā hualoaʻa ma ka dehydrogenation o ka unsaturated hydrocarbon, no a hiki i ka helu ana i ka mau haʻilula CnH2n-2. Polymerization o unsaturated CxHy mea he hanalima kaʻina no ka hana i ka kemikala pīlali hoʻohana ma o ka laholio.

Ma waena o ka no nā hana o ka pono o ka paʻa kūhohonu loa alkanes, typified ma maʻamau pentane, anao? Aou a me ka hoʻohana 'ana o kēia hui me he wāwahie wahie. Ma ka hopena, no ka poeikohoia o ka palena o ka helu ana o hydrocarbons, isomerism Ua ano o ka papa kuhikuhiE huakai kaapuni. Aie i ka mea i ka lātoma mea i papalua paa ana, no ka paraffin i typical geometrical isomers, oa ka mea,ʻaʻohe Kisa no lakou, a māhū isomers.
