Which salt of carboxylic acid will be required to prepare ethane by sodalime decarboxylation? Give equation for the reaction.

Explanation

To prepare ethane by soda lime decarboxylation, we need to identify the appropriate sodium salt of a carboxylic acid. The process of decarboxylation involves the removal of carbon dioxide (CO2) from the sodium salt of the carboxylic acid when heated with soda lime (a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO)).

### Step-by-Step Solution:

1. **Understanding Decarboxylation**:
- Decarboxylation is the process of removing a carboxyl group (-COOH) from a carboxylic acid, resulting in the formation of an alkane and carbon dioxide.

2. **Identifying the Alkane**:
