Question

In Wurtz reaction in the preparation of alkanes, metallic sodium acts as:
  1. dehydrogenating agent
  2. oxidizing agent
  3. dehydrohalogenating agent
  4. reducing agent

A
reducing agent
B
dehydrogenating agent
C
oxidizing agent
D
dehydrohalogenating agent
Solution
Verified by Toppr

Wurtz reaction: RX+2Na+XRRR+2NaX

In Wurtz reaction:
An ether solution of an alkyl halide is treated with sodium to give alkanes.

Here sodium act as reducing agent. (metals easily lose electrons)

Option B is correct.
