Name the reagent used in Wurtz Reaction

The correct answer is Option (1) → Sodium in dry ether.

The Wurtz reaction is used to couple two alkyl halides to form a higher alkane.

In this reaction, sodium metal in dry ether acts as a reducing agent, causing the halide ions to be removed from the alkyl halides, and the remaining alkyl groups combine to form a new carbon-carbon bond.

Example

When two molecules of methyl bromide \((CH_3Br)\) react with sodium in dry ether, ethane \((CH_3CH_3)\) is formed:

Thus, sodium in dry ether is the reagent used in the Wurtz reaction.
