Question

During dehydration of alcohols to alkenes by heating with concentrated H2SO4 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+ mathopO H2)

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 $(- O H)$ into good leaving group $(- O + H_{2})$
