Question
What is the action of following reagents on ethanoic acid?
sodalime/heat
Solution
Sodium salts of ethanoic acid on heating with soda lime give methane which contains one carbon atom less than the ethanoic acid.
\[\ce{\underset{\text{Ethanoic acid}}{CH3 - COOH} ->[NaOH] \underset{\text{Sodium acetate}}{CH3 - COO- Na+} + NaOH ->[CaO][\Delta] \underset{\text{Methane}}{CH4} + Na2CO3}\]
