The major product of the following reaction sequence is

Step-by-step solution

- OCH 3 is an electron donating group. It is an activating group. Activating group gives the aromatic electrophilic substitution reaction at the para position is a major product. In step - 1 , there is Friedel-Craft's Acylation of anisole to form 4-Methoxy acetophenone(major product) In step - 2 , 4-Methoxy acetophenone is converted to 4-Ethyl anisole in by Clemmensen reduction using zinc amalgam and concentrated hydrochloric acid. In step-3, cleavage with HI converts 4-Ethyl anisole to the 4-ethyl phenol. Reac
