Which one of the following statements is incorrect regarding acetal and ketal formation when Propanal and Propanone are separately reacted with Ethanol in presence of anhydrous HCl gas.

Step-by-step solution

Propanal is an aldehyde and Propanone is a ketone. Aldehydes are more reactive towards nucleophilic addition than ketones due to both steric and electronic factors. Thus, the rate of acetal formation from propanal is greater than the rate of ketal formation from propanone. Both reactions involve the nucleophilic attack of ethanol on the carbonyl carbon, which is a nucleophilic addition reaction. Acetal formation is a reversible reaction. To shift the equilibrium towards the product (acetal), an excess of alcohol is
