Question

Formation of methyl tertiary butyl ether by the reaction of sodium tertiary butoxide and methyl bromide involves

• A. elimination reaction
• B. electrophilic addition reaction
• C. nucleophilic substitution unimolecular reaction
• D. nucleophilic substitution bimolecular reaction

Answer 1

Answer: (D)

nucleophilic substitution bimolecular reaction

Answer 2

The reaction takes place as
Since, in this reaction, $Br ^{-}$is substituted by the attack of nucleophile $\left( CH _{3}\right)_{3} CO ^{-}$, it is a nucleophilic substitution reaction. Moreover, the rate of the reaction depends upon the concentration of $\left( CH _{3}\right)_{3} CO ^{-}$and $CH _{3} Br$ both, so it is a bimolecular reaction.
