Q. Assertion : Sodium salt of butanoic acid on heating with soda lime gives butane.
Reason : Decarboxylation reaction yields alkanes having same number of carbon atoms as the parent acid.

Hydrocarbons

Solution:

Decarboxylation reaction gives alkanes having one carbon atom less than the carboxylic acid. Therefore, sodium salt of butanoic acid on heating with soda lime gives propane.
