Based on the electronic and steric effects, which of the following represents the correct decreasing order of reactivity towards nucleophilic addition?
Q1. Based on the electronic and steric effects, which of the following represents the correct decreasing order of reactivity towards nucleophilic addition?
Answer: Methanal > Ethanal > Propanone
Explanation: Formaldehyde is the most reactive due to lack of electron-donating alkyl groups and minimal steric hindrance. Higher ketones are the least reactive.
