"<p>Alpha halogenation involves the addition of a halogen atom to the &alpha; carbon in an aldehyde or ketone. This reaction typically proceeds via an enol intermediate, where the&nbsp;&alpha; carbon becomes nucleophilic due to the presence of the electron-withdrawing carbonyl group. The halogenation occurs through nucleophilic attack by a halogen source, such as bromine or chlorine, on the enol intermediate, followed by deprotonation to yield the alpha-halogenated carbonyl compound.</p>"
