Question: In the following reaction
Rate of the reaction is the highest for:
Acetone as substrate and methanol in excess.
Propanal as substrate and methanol in stoichiometric amount.
Propanal as substrate and methanol in excess.
Acetone as substrate and methanol in stoichiometric amount.
Correct Option: , 3
Solution:
Generally, aldehydes are more reactive than ketones in nucleophilic addition reactions.
$\therefore$ Rate of reaction with alcohol to form acetal and ketal is
