Vedclass · Answer

(A) Dewar's benzene is a valence isomer of benzene. When treated with an acid catalyst like $H^+$ or a Lewis acid like $AlCl_3$,it undergoes rearrangement to form the most stable isomer,which is benzene. The reaction proceeds through the protonation of a double bond followed by a skeletal rearrangement to form the aromatic benzene ring.

$A$ and $B$ are isomers. Product $B$ is: (Dewar's Benzene is $A$)
