प्रश्न
Which will undergo faster nucleophilic addition reaction?
Acetaldehyde or Propanone
Advertisements
उत्तर
Aldehydes are generally more reactive than ketones in nucleophilic addition reactions due to steric hindrance. As the electron density at the carbonyl carbon increases, the +I effect increases, which decreases the chances of attack by a nucleophile. Thus, acetaldehyde is more reactive than propanone.
