Vedclass · Answer

(B) The reaction sequence is as follows:$1$. Phenol $(C_6H_6O)$ undergoes catalytic hydrogenation with $H_2/Ni$ to form cyclohexanol $(A)$.$2$. Cyclohexanol $(A)$ is oxidized using $Cu$ (dehydrogenation) to form cyclohexanone $(B)$.$3$. Cyclohexanone $(B)$ reacts with hydroxylamine $(NH_2OH)$ to form cyclohexanone oxime $(C)$.$4$. Cyclohexanone oxime $(C)$ undergoes Beckmann rearrangement in the presence of acid $(H^+)$ to form caprolactam $(D)$.$5$. Caprolactam $(D)$ undergoes ring-opening polymerization in the presence of base $(HO^-)$ to form Nylon $6$ $(E)$.
