Vedclass · Answer

(B) The reaction is an example of the Pinacol-Pinacolone rearrangement.In the presence of an acid $(H^{+})$,$2,3$-dimethylbutane-$2,3$-diol (Pinacol) undergoes dehydration and rearrangement to form $3,3$-dimethylbutan-$2$-one (Pinacolone).The mechanism involves the protonation of one of the hydroxyl groups,followed by the loss of a water molecule to form a carbocation.Then,a methyl group shifts to the adjacent carbon atom,followed by the loss of a proton to form the final ketone product,$CH_3-CO-C(CH_3)_3$.

$CH_3-C(CH_3)(OH)-C(CH_3)(OH)-CH_3 \xrightarrow[H^{+}]{\Delta} ?$
