Question

Sodium salt of acetic acid is converted into methane by

• A. dehydrogenation
• B. decarboxylation
• C. polymerization
• D. dehydration

Answer 1

The correct option is B decarboxylation

Decarboxylation reaction is defined as a chemical reaction that eliminates a carboxyl group and liberates carbon dioxide $\left(C{O}_2\right)$. Decarboxylation mostly refers to a reaction of carboxylic acids erasing a carbon atom from a chain of carbons. The reagents used in the reaction are NaOH and CaO in 3:1 ratio in presence of heat.

The reaction is as follows:

Hence, the correct answer is option (b).
