Vedclass · Answer

(D) The reaction of a Grignard reagent $(RMgX)$ with carbon dioxide $(CO_2)$ is a nucleophilic addition reaction.The nucleophilic alkyl group $(R^-)$ of the Grignard reagent attacks the electrophilic carbon atom of $CO_2$.This results in the formation of an intermediate carboxylate salt,which is $RCOO^{-}Mg^{+}X$ (often written as $RCOOMgX$).Subsequent acid hydrolysis $(H_3O^{+})$ of this intermediate yields the corresponding carboxylic acid $(RCOOH)$.

$RMgX + CO_2$ $\xrightarrow[\text{dry}]{ \text{ether} } Y$ $\xrightarrow{ H_3O^{+} } RCOOH$
What is $Y$ in the above reaction?
