Vedclass · Answer

(A) The reaction shown is the Wurtz reaction,which is used to prepare higher alkanes from alkyl halides. In this reaction,two molecules of an alkyl halide $(R' - X)$ react with metallic sodium $(Na)$ in the presence of dry ether to form a symmetrical alkane $(R' - R')$ and sodium halide $(NaX)$. The general equation is: $2R' - X + 2Na \xrightarrow{	ext{dry ether}} R' - R' + 2NaX$. Therefore,the product formed is $R' - R'$.

The provided image shows a chemical reaction: $R' - X \xrightarrow{Na / \text{ether}} ?$. This is the Wurtz reaction. Identify the product formed in this reaction.
