Question

preparation of alkanes by the decarboxylation of acid salts​

Answer 1

Answer:

Preparation of Alkanes from Carboxylic Acids

Decarboxylation : Sodium salts of carboxylic acids (RCOONa) on heating with soda lime (NaOH + CaO) form alkanes containing one carbon atom less than the salt. CaO is used to keep NaOH dry as NaOH tends to absorb moisture from air.
