(c)Benzoic acid, benzoyl chloride, and benzoic anhydride have been prepared in parts (a) and (b)of this problem. Any of them could be converted to benzyl benzoate on reaction with benzylalcohol. Thus the synthesis of benzyl benzoate requires the preparation of benzyl alcohol fromtoluene. This is effected by a nucleophilic substitution reaction of benzyl bromide, in turn pre-pared by halogenation of toluene.Alternatively, recall that primary alcohols may be obtained by reduction of the correspondingcarboxylic acid.Then(d)Benzamide is prepared by reaction of ammonia with either benzoyl chloride from part (a) orbenzoic anhydride from part (b).(e)Benzonitrile may be prepared by dehydration of benzamide.(f)Benzyl cyanide is the product of nucleophilic substitution by cyanide ion on benzyl bromideor benzyl chloride. The benzyl halides are prepared by free-radical halogenation of the toluene
