(B) The Wurtz reaction involves the coupling of alkyl halides in the presence of sodium and dry ether. When a mixture of ethyl iodide $(C_2H_5I)$ and $n$-propyl iodide $(C_3H_7I)$ is used,the following coupling reactions occur: $1$. $C_2H_5I + C_2H_5I \xrightarrow{Na/dry ether} C_4H_{10}$ ($n$-butane) $2$. $C_3H_7I + C_3H_7I \xrightarrow{Na/dry ether} C_6H_{14}$ ($n$-hexane) $3$. $C_2H_5I + C_3H_7I \xrightarrow{Na/dry ether} C_5H_{12}$ ($n$-pentane) Thus,$n$-butane,$n$-hexane,and $n$-pentane are formed,while propane is not formed.

$A$ mixture of ethyl iodide and $n$-propyl iodide is subjected to Wurtz reaction. The hydrocarbon which will not be formed is
