Consider the given reactions: i. RCNReduction−−−−−−→A ii. RCN(i) CH3MgBr−−−−−−−−→(ii)H2OB iii. RCNHydrolysis−−−−−−→(Partial)C iv. RCN(i) Reduction−−−−−−−−→(ii) HONOD Based on the products of the reactions, we have:
An organic compound (A) on reduction gives compound (B). (B) on treatment with CHCl3 and alcoholic KOH gives (C). (C) on catalytic reduction gives N - methyl aniline. The compound 'A' is
