Organic: Aldehydes, Ketones and Carboxylic Acids

Question:

What is the medium of the nucleophilic addition reactions in the aldehydes?

Options:

Acidic 

Basic 

Extremely basic 

Weakly basic 

Correct Answer:

Acidic 

Explanation:

In the case of aldehydes, when the incoming nucleophile is weak, the acidic medium helps in protonation by increasing the positive charge on the carbonyl carbon so that it is more susceptible to attack by relatively weaker nucleophiles.
