Hint:
Benzonitrile is the chemical compound which is a colorless liquid with a sweet almond odor whereas benzophenone is a white solid that is soluble in organic solvents.

Complete step by step answer:
-Conversions are described as ratios of how much of a reactant has reacted, how much of a desired product was formed in ratio to the undesired product.
-Benzonitrile reacts with phenyl magnesium bromide in presence of dry ether to give an imine complex which on acid hydrolysis gives benzophenone.
-During the reaction benzonitrile and phenyl magnesium bromide should be taken in equimolecular proportion.

Benzophenone can also be prepared by Friedel-Crafts acylation of benzene with benzoyl chloride in the presence of a Lewis acid. (Example aluminium chloride) catalyst.

Note:
Benzophenone is used as an ultraviolet curing agent, flavor ingredient, fragrance enhancer and perfume fixate, and as an additive for plastics, coatings and adhesive formulations. Further, benzonitrile is used as a speciality solvent and to make other chemicals.
