Question

6. How alkanes are prepared from alkyl halides? Write specific reaction to explain.​

Answer 1

Answer:

Preparation of Alkanes from alkyl halides:

Alkane can be produced from alkyl halides predominantly by two ways:

1. Alkanes can be prepared from alkyl halides (except fluorides) through reduction with zinc and dilute hydrochloric acid.

dry ether

CH-Br+2Na+BrCH3----------------> CH3-CH3+2NaBr

Wurtz reaction: In dry ethereal solution, on treating alkyl halides with sodium metal, production of alkanes is higher. By this reaction, we can achieve higher alkanes with an even number of carbon atoms.
