Answer:

$\Huge \underline {\red {\bf{Answer}}}$

Grignard reagent reacts with solid CO2 (dry ice) to form magnesium salt of carboxylic acid. This is followed by acidification to obtain carboxylic acid. For example, the reaction between methyl magnesium bromide and carbon dioxide followed by acid hydrolysis will give acetic acid.
