Vedclass · Answer

(B) $2, 2-$dimethylbutane is prepared using the Corey-House synthesis, which involves the reaction of a lithium dialkylcuprate with an alkyl halide.To prepare $2, 2-$dimethylbutane $(CH_3-C(CH_3)_2-CH_2-CH_3)$, we need a tert-butyl group and an ethyl group.The Corey-House reaction follows an $S_N2$ mechanism, which works best with primary alkyl halides.Therefore, the reaction between $(Me_3C)_2CuLi$ and $MeCH_2Br$ is the most efficient route.The reaction is: $(Me_3C)_2CuLi + MeCH_2Br \rightarrow Me_3C-CH_2CH_3 + Me_3CCu + LiBr$.

The best method for the preparation of $2, 2-$dimethylbutane is via the reaction of
