Which of the following is NOT formed when a mixture of methyl bromide and n-propyl bromide is treated with sodium metal in dry ether?
- Butane
- Propane
- Ethane
- Hexane
Solution
$\begin{gathered}
\mathrm{CH}_3-\mathrm{Br}+\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{Br} \underset{\text { dry ether }}{\longrightarrow} \mathrm{CH}_3-\mathrm{CH}_3 \text { ethane } \\
\qquad \mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_3 \text { n-hexan } \\
\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_3 \text { n-butane }
\end{gathered}$
Thus, propane is not formed.
