Vedclass · Answer

(D) The reaction of $3-$phenylpropane $-1,2-$diol with $H_2SO_4$ involves the dehydration of the vicinal diol. Under acidic conditions and heating,the diol undergoes intramolecular dehydration to form an epoxide (oxirane derivative). The hydroxyl group at the $C-1$ position is protonated,followed by the nucleophilic attack of the $C-2$ hydroxyl group on the $C-1$ carbon,leading to the elimination of water and the formation of the epoxide ring. The product is $2-$benzyl oxirane.

What is the major product obtained when $3-$phenylpropane $-1,2-$diol is heated with $H_2SO_4$?
