Answer 2

$\huge\textcolor{orange}{\texttt{Answer :-}}$

The process of removal of a molecule of CO2 to form a carboxylic acid is called decarboxylation.

It is usually carried out by heating a mixture of a carboxylic acid or its sodium salt with soda lime (NaOH + CaO)

Example :

$CH_3CH_2COONa + NaOH -----) CH_3CH_3 + Na_2CO_3$

NOTE : This reaction takes place under the presence of CaO & heat energy.
