Concept:

Thus, both benzyl cyanide and benzyl isocyanide are the products of reaction but the benzyl isocyanide being the major product gives the correct option i.e. option (d).

Benzyl chloride is an organic compound with the formula C6H5CH2Cl. This colourless liquid is a reactive organic chlorine compound that is widely used chemical building block.

Benzyl chloride is prepared industrially by the gas-phase photochemical reaction of toluene with chlorine.

Benzyl chloride.

Benzyl isocyanide was used in the synthesis of RU(ll) complexes containing hydrazine and benzyl isocyanide ligands. It was used in a three component coupling process leading two and N-arylamides.

Benzyl isocyanide forms phosphaalkene containing complexes.

Benzyl chloride is the precursor to benzyl esters which are used as plasticizers, flavorants, and perfumes. Phenylacetic acid, a precursor to pharmaceuticals, is produced from benzyl cyanide, which is generated by treatment of benzyl chloride with sodium cyanide. Quaternary ammonium salts, used as surfactants are readily formed by alkylation of tertiary amines with benzyl chloride.
