On treatment with sodium borohydride propane gives?.....????????

Answer 1

On treatment with sodium borohydride propane

Explanation:

Sodium Borohydride ($NABH_{4}$) is an effective reducing agent used to reduce aldehydes, ketones and acyl chloride with the incapability to reduce esters, carboxylic acid and amides.  

Thus we find that it has no specific reaction over alkanes and thus no formation of a new product is seen when it is added to Propane.

On treatment with sodium borohydride propane gives nothing as there is no reaction.
