(b)
Interpretation: The synthesis of given compound from aniline as starting material is to be devised.
Concept introduction: The formation of diazonium salt from aromatic amines takes place using sodium nitrite and hydrochloric acid at low temperatures. This process is known as diazotization. The diazonium salts can be converted to aryl halides using cuprous halides or aryl cyanides using cuprous cyanides.
Friedel-Crafts alkylation permits the synthesis of alkylated products by the reaction of arenes with alkyl chlorides in the presence of aluminium chloride (Lewis acid). This alkylation reaction comes under the category of electrophilic aromatic substitution.

The diazonium salts can be converted to aryl halides using cuprous halides or aryl cyanides using cuprous cyanides.
Diazonium salts form azo compounds with aromatic phenols or aromatic amines.
Friedel-Crafts alkylation permits the synthesis of alkylated products by the reaction of arenes with alkyl chlorides in the presence of aluminium chloride (Lewis acid). This alkylation reaction comes under the category of electrophilic aromatic substitution.
