Question
Write a note on Wurtz reaction and its Limitations.
✓
Answer
→ Alkyl halides react with sodium in dry ether to give hydrocarbons containing double the number of carbon atoms present in the halide.
→ This reaction is known as Wurtz reaction.
$2 RX +2 Na \xrightarrow[\text { ether }]{\text { dry }} R - R +2 NaX$
Limitation:
(1) This method is suitable to produce an alkane only with even number of carbon.
(2) If alkyl halide is tertiary, the alkene is major product.
