- 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 suav los ntawm qhov kawg ze tshaj ntawm ob daim ntawv cog lus carbon atom.
Ntawm no, ua li cas koj thiaj li hu ua alken compound?
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.
Tsis tas li ntawd, benzene yog Cycloalkene? Benzene yog ib qho tshuaj tsw qab thiab Cycloalkene yog ib qho aliphatic cyclic compound. Yog lawm tshuaj benzene tuaj yeem raug hu ua 1, 3, 5 cyclohexatriene.
Hais txog qhov no, koj ua li cas lub npe alken uas muaj ntau ob daim ntawv cog lus?
Qhia qhov ob daim ntawv cog lus los ntawm tus naj npawb ntawm thawj alkene carbon. 5. Yog ntau tshaj ib ob daim ntawv cog lus yog tam sim no, qhia lawv txoj hauj lwm los ntawm kev siv tus naj npawb ntawm thawj carbon ntawm txhua tus ob daim ntawv cog lus thiab siv lub ntsiab lus -diene (rau 2 ob daim ntawv cog lus ), -triene (rau 3 ob daim ntawv cog lus ), -tetraene (rau 4 ob daim ntawv cog lus ), thiab lwm yam.
Lwm lub npe ntawm alkyne yog dab tsi?
acetylene

Xav txog thawj daim duab: lub xub nkhaus yog kos los ntawm qhov tseem ceeb tshaj plaws (1) hloov mus rau qhov tseem ceeb tshaj plaws (4) hloov pauv
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.

Koj sau cov npe tshuaj thiab cov qauv li cas?
Thaum sau cov mis, qhov zoo atom lossis ion los ua ntej los ntawm lub npe ntawm qhov tsis zoo ion. Lub npe tshuaj rau cov lus ntsev yog sodium chloride. Lub sij hawm lub sij hawm qhia tau hais tias lub cim rau sodium yog Na thiab lub cim rau chlorine yog Cl. Cov tshuaj formula rau sodium chloride yog NaCl
Dab tsi yog qhov txawv ntawm cis thiab trans isomers ntawm alkenes?
Cis isomers yog cov molecules nrog tib qhov sib txuas ntawm atoms. Lawv txuas ntxiv muaj cov pab pawg zoo ib yam feem ntau ntawm tib sab. Ib tug trans isomer muaj molecules nrog ob tib atoms tab sis nyob rau hauv opposite sab ntawm ob daim ntawv cog lus. Nws yog feem ntau ntawm lub sij hawm ib tug polar molecule
