Vedclass · Accepted Answer

$t-BuO^{-}K^{+}$ on reaction with $CH_3-Br$ gives $CH_3-C(CH_3)=CH_2$ as the major product

Vedclass · Answer

(D) $t-BuO^{-}K^{+}$ is a strong bulky base,but $CH_3-Br$ is a methyl halide. Since methyl halides do not have $\beta$-hydrogens,elimination $(E2)$ is not possible. The reaction proceeds via $S_N2$ mechanism to form an ether $(t-Bu-O-CH_3)$ as the major product. $t-BuO^{-}K^{+} + CH_3-Br \rightarrow t-Bu-O-CH_3 + KBr$. Therefore,the statement that it gives isobutylene $(CH_3-C(CH_3)=CH_2)$ is incorrect.
