Vedclass · Answer

(B) The reaction of a Grignard reagent $(RMgX)$ with dry ice $(CO_2)$ followed by acidic hydrolysis is a standard method for the preparation of carboxylic acids.In this reaction,the nucleophilic alkyl group $(CH_3CH_2^-)$ of the Grignard reagent attacks the electrophilic carbon atom of $CO_2$ to form a magnesium carboxylate salt $(CH_3CH_2COO^-Mg^+Br^-)$.Subsequent hydrolysis with dilute $HCl$ converts the salt into the corresponding carboxylic acid.$CH_3CH_2MgBr + CO_2 \rightarrow CH_3CH_2COOMgBr$$CH_3CH_2COOMgBr + H_2O/H^+ \rightarrow CH_3CH_2COOH + Mg(OH)Br$The product formed is $CH_3CH_2COOH$,which is Propanoic acid.
