Vedclass · Answer

(D) Grignard reagent has the general formula $R-Mg-X$,where $R$ is an alkyl or aryl group,$Mg$ is magnesium,and $X$ is a halogen $(Cl, Br, I)$.Grignard reagents are highly reactive towards acidic protons,such as those found in carboxylic acids ($-COOH$ group).Therefore,a $-COOH$ group cannot be present in a Grignard reagent because it would immediately react with the reagent to form an alkane and a magnesium salt.
