Question
The major product in the reaction is
The correct answer is:
CH3O– is a strong nucleophile as well as a strong base. Therefore, it can either bring about substitution or elimination. Since the CH3 group at b-carbon causes stearic hindrance to nucleophilic substitution (SN2), therefore, elimination occurs preferably to form 2- mehtylpropene
