Chemistry Question on Methods of Preparation of Haloalkanes

Wurtz's reaction involves'the reduction of alkyl halide with:

A

 Zn/HCl~Zn/HCl

B

HIHI

C

Zn/CuZn/Cu couple

D

Na in ether

Answer

Na in ether

Explanation

Solution

Write Wurtz reaction 2RXalkylhalide+2NaSodiumehterRRalkane+2NaX\underset{\text{alkyl}\,\text{halide}}{\mathop{2R-X}}\,+\underset{\text{Sodium}}{\mathop{2Na}}\,\xrightarrow{\text{ehter}}\underset{\text{alkane}}{\mathop{R-R}}\,+2NaX \therefore Na in ether'is correct answer.
