(D) The reaction of a mixture of alkyl halides with sodium in dry ether is known as the Wurtz reaction. When a mixture of $CH_3Br$ and $C_2H_5Br$ is used, the following coupling reactions occur:$1$. $CH_3Br + 2Na + CH_3Br ightarrow CH_3-CH_3 (	ext{Ethane}) + 2NaBr$$2$. $C_2H_5Br + 2Na + C_2H_5Br ightarrow C_2H_5-C_2H_5 (n	ext{-Butane}) + 2NaBr$$3$. $CH_3Br + 2Na + C_2H_5Br ightarrow CH_3-C_2H_5 (	ext{Propane}) + 2NaBr$Since $2$-methyl propane (isobutane) is a branched alkane, it cannot be formed by the simple coupling of these linear alkyl halides. Thus, it is not obtained.

Which of the following compounds is not obtained when a mixture of $CH_3Br$ and $C_2H_5Br$ is treated with sodium metal in the presence of dry ether?
