Lub ene suffix (qhov xaus) qhia ib alkene los yog cycloalkene. Cov saw ntev tshaj plaws xaiv rau hauv paus npe yuav tsum suav nrog ob qho tib si carbon atom ntawm ob daim ntawv cog lus. Lub hauv paus saw yuav tsum tau suav los ntawm qhov kawg ze tshaj ntawm ob daim ntawv cog lus carbon atom.
Ua raws li qhov no hauv kev txiav txim siab, ua li cas koj lub npe alkenes?
Lub npe Alkenes thiab Alkynes
- Alkenes thiab alkynes muaj npe los ntawm kev txheeb xyuas cov saw ntev tshaj plaws uas muaj ob lossis peb daim ntawv cog lus.
- Cov saw hlau raug suav ua kom txo qis tus lej muab rau ob lossis peb daim ntawv cog lus.
- Lub ntsiab lus ntawm lub compound yog "-ene" rau ib qho alkene lossis "-yne" rau ib qho alkyne.
Ib tug kuj yuav nug, ua li cas koj lub npe hloov pauv alkene? Cov Cai Tseem Ceeb
- Nrhiav qhov ntev Carbon Chain uas muaj cov Carbon Carbon ob daim ntawv cog lus.
- Muab tus lej qis tshaj plaws rau Carbon Carbon ob daim ntawv cog lus.
- Ntxiv cov hloov pauv thiab lawv txoj haujlwm rau alkene ua ntej.
- Tom ntej no yog txheeb xyuas cov stereoisomers.
Tsis tas li ntawd, ua li cas koj lub npe cycloalkenes thiab alkenes?
Cycloalkenes muaj npe zoo ib yam. Number tus cycloalkene yog li ob daim ntawv cog lus carbons tau txais tus lej 1 thiab 2, thiab thawj qhov hloov pauv yog tus lej qis tshaj plaws. b. Yog tias muaj kev hloov pauv ntawm ib qho ntawm ob daim ntawv cog lus carbons, nws tau txais tus lej 1.
Koj npe bicyclic alkenes li cas?
Txhawm rau hu ua bicyclic alkanes, koj ua raws li peb kauj ruam no:
- Suav tag nrho cov carbons nyob rau hauv tag nrho cov molecule. Qhov no yog niam txiv lub npe (eg.
- Suav tus naj npawb ntawm cov pa roj carbon monoxide ntawm tus choj taub hau, tom qab ntawd muab tso rau hauv cov hlua khi hauv nqes mus. (eg.
- Muab lo lus bicyclo rau ntawm qhov pib ntawm lub npe.

Dab tsi alkenes muaj nyob rau hauv lawv cov npe?
Nws yog lub npe siv tib lub qia raws li alkane muaj tib tus naj npawb ntawm cov pa roj carbon atoms tab sis xaus rau hauv -ene kom paub tias nws yog alkene. Yog li cov compound CH 2 = CHCH 3 yog propene. 13.1: Alkenes: Cov Qauv thiab Cov Npe.

Dab tsi yog cov cai hauv kev naming alkynes?
Cov ntsiab lus tseem ceeb Alkenes thiab alkynes muaj npe los ntawm kev txheeb xyuas cov saw ntev tshaj plaws uas muaj ob lossis peb daim ntawv cog lus. Cov saw hlau raug suav ua kom txo qis tus lej muab rau ob lossis peb daim ntawv cog lus. Lub ntsiab lus ntawm lub compound yog "-ene" rau ib qho alkene lossis "-yne" rau ib qho alkyne
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Tam sim no universal naming system siv rau naming kab mob yog dab tsi?
Nyob rau hauv 1758, Linnaeus tau npaj ib qho kev faib cov kab mob. Nws luam tawm nyob rau hauv nws phau ntawv, Systema Naturae. Hauv qhov system no, txhua hom tau muab lub npe ob feem; Vim li no, qhov system hu ua binomial nomenclature. Cov npe yog raws li cov lus thoob ntiaj teb: Latin
