Rate of the reaction is the highest for :
Rate of the reaction is the highest for :Propanal as substrate and methanol in
stoichiometric amount.
Acetone as substrate and methanol in
stoichiometric amount
Propanal as substrate and methanol in
excess
Acetone as substrate and methanol in excess
Explanation
Steric hindrance of aldehydes is less compares to the ketone that is why aldehydes are more reactive than
ketones in nucleophilic addition reactions.
So among propanal and acetone, propanal is suitable as substance.
And to form acetal, excess amount of alcohol is required so here methanol in excess is required.
