Vedclass · Answer

(D) The reaction proceeds via the formation of an oxime with $NH_2OH, HCl$. Treatment with $PCl_5$ causes the Beckmann rearrangement. The oxime can exist as two stereoisomers ($syn$ and $anti$ to the alkyl chain). Migration of the alkyl group leads to the cyclic imine (product $c$). Migration of the aryl group leads to the amide (product $a$ and $b$ depending on the specific isomer). Since the question asks to consider minor products as well,all these products are formed in the reaction mixture.
