Vedclass · Answer

(B) The reaction is a $Pinacol-Pinacolone$ rearrangement,which is an intramolecular process.In this reaction,the carbocation formed from the diol rearranges to the corresponding ketone without exchanging alkyl or aryl groups between different molecules.For $(A)$,the product is $Ph-C(Ph)(CH_3)-CO-CH_3$ $(p)$.For $(B)$,the product is $Ph-C(Ph)(Et)-CO-Et$ $(q)$.Since the process is intramolecular,no crossover products like $(r)$ or $(s)$ are formed.Therefore,the correct products are $(p)$ and $(q)$.

$Ph-C(OH)(Ph)-C(OH)(CH_3)_2$ $(A)$ $+$ $Ph-C(OH)(Ph)-C(OH)(Et)_2$ $(B)$ $\xrightarrow{H_2SO_4}$
$(p)$ $Ph-C(Ph)(CH_3)-CO-CH_3$
$(q)$ $Ph-C(Ph)(Et)-CO-Et$
$(r)$ $Ph-C(Ph)(Et)-CO-CH_3$
$(s)$ $Ph-C(Ph)(CH_3)-CO-Et$
When $(A)$ and $(B)$ react with $H_2SO_4$,the products obtained are:
