The structure for the ternary complex is to be proposed and all the products of the reaction, when carbonyl group is attacked by a Grignard reagent, is to be written. Concept Introduction: ▸ The general formula of the Grignard reagent is R-Mg-X, where R is any alkyl or aryl group and X is the halogen. ▸ The Grignard reagent acts as a strong nucleophile, easily reacting with electrophiles like aldehydes , ketones and ester. ▸ The group C = O is known as the carbonyl group. The aldehyde and ketone functional groups contain the carbonyl group.
