Question

Identify X, Y and Z in the following sequence of reactions:

\[\ce{C6H5Cl->[CuCl, HCl][]X->[CuCn][Pyridine, Δ]Y->[Dil{.}HCl][]Z}\]

Answer 1

\[\ce{C6H5Cl ->[CuCl, HCl][]\mathbf{\underset{\text{Chlorobenzene}}{C_6H_5Cl}} ->[CuCN][Pyridine, \Delta]\mathbf{\underset{\text{Benzonitrile}}{C_6H_5CN}} ->[Dil{.}HCl][]\mathbf{\underset{\text{Benzoic acid}}{C_6H_5COOH}}}\]
