Lub cev qhuav dej ntawm cawv muab cov alkene ruaj khov (ntau hloov pauv) ua cov khoom loj. Cov khoom loj yog 1-methylcyclohexene thiab methylenecyclohexane yog cov khoom me.

Yuav ua li cas thaum alkene dehydrated?

Mechanism for the Dehydration of Alcohol into Alkene

This ion acts ua ib pab pawg zoo heev uas tawm mus tsim cov carbocation. Lub deprotonated acid (lub nucleophile) ces tawm tsam cov hydrogen nyob ib sab ntawm carbocation thiab tsim ib daim ntawv cog lus ob.

Dab tsi tuaj yeem ua kom lub cev qhuav dej kom tsim tau alkene?

Lub cev qhuav dej ntawm Alcohols rau Yield AlkenesIb txoj hauv kev los ua ke alkenes yog los ntawm lub cev qhuav dej ntawm cawv, txheej txheem uas cov cawv tau txais E1 lossis E2 cov txheej txheem kom poob dej thiab tsim ob daim ntawv cog lus.

Yuav ua li cas yog cov khoom ntawm lub cev qhuav dej?

D. Cov tshuaj tiv thaiv lub cev qhuav dej yog cov tshuaj tiv thaiv ntawm ob lub tebchaw uas ib qho ntawm cov khoom yog water . Piv txwv li, ob lub monomers yuav hnov mob qhov twg hydrogen (H) los ntawm ib lub monomer khi rau ib pawg hydroxyl (OH) los ntawm lwm cov monomer los ua ib qho dimer thiab dej molecule (H 2 O).

Dab tsi yog cov khoom tseem ceeb ntawm lub cev qhuav dej?
