Vedclass · Answer

(D) Grignard reagents $(R-Mg-X)$ are organometallic compounds that are highly reactive towards protic sources like water $(H_2O)$,alcohols $(R-OH)$,or acids $(R-COOH)$.When a Grignard reagent reacts with water,it undergoes a rapid acid-base reaction to form an alkane $(R-H)$ and a metal hydroxide halide $(Mg(OH)X)$.The reaction is: $R-Mg-X + H_2O \rightarrow R-H + Mg(OH)X$.Therefore,the presence of water destroys the Grignard reagent,making ether an essential non-protic solvent for its preparation.
