Question

During dehydration of alcohols to alkenes by heating with concentrated H 2 SO 4 the initiation step is : (A) protonation of alcohol molecule (B) formation of carbocation (C) elimination of water (D) formation of an ester

Tardigrade Admin · Accepted Answer

Protonation of - OH is first step. Conversion of poor leaving group (-OH) into good leaving group (- overset+OH2)

Q. During dehydration of alcohols to alkenes by heating with concentrated $H_{2} S O_{4}$ the initiation step is :

protonation of alcohol molecule

formation of carbocation

elimination of water

formation of an ester

Protonation of $- O H$ is first step. Conversion of poor leaving group (-OH) into good leaving group $(- O + H_{2})$
