The mechanism for nucleophilic addition to aldehydes and ketones under different reaction conditions is that Before a weak nucleophilic assault may happen, the target must undergo protonation.

A nucleophile establishes a sigma bond with an electron-deficient molecule in a chemical addition process known as a nucleophilic addition reaction. The ability to transform carbonyl groups into a variety of functional groups makes these reactions crucial in organic chemistry.

An intermediate alkoxide is created by the breakdown of the p link to the O. The intermediate alkoxide is protonated to produce an alcohol derivative.

Therefore, the order changes to II > V > I > IV > III because nucleophilic addition is directly proportional to the electron deficiency on the carbonyl carbon.

The addition of the nucleophile and H across the C=O double bond is the outcome of all forms of nucleophile reactions.
