Question

Which one is most reactive towards nucleophilic addition reaction?

Options

• 

• 

• 

• 

Answer 1

Explanation:

Aromatic aldehydes react to nucleophilic addition more readily than aromatic ketones. As a result, benzaldehyde (C₆H₅CHO) has a higher nucleophilic addition reactivity than acetophenone (C₆H₅COCH₃). The presence of electron donating groups such as −CH₃, −C₂H₅ in aromatic aldehydes discourages nucleophilic assault because the carbonyl carbon becomes less electrophilic.
