What does “Nucleophilic addition to carbonyls” actually mean in Aldehydes, Ketones & Carboxylic Acids, and why does it matter for JEE?

the polar C=O group is attacked by nucleophiles at carbon; aldehydes react faster than ketones.

In simple words: the polar C=O group is attacked by nucleophiles at carbon; aldehydes react faster than ketones. Getting Nucleophilic addition to carbonyls clear matters because JEE questions on Aldehydes, Ketones & Carboxylic Acids usually test this idea directly, not just a formula you memorised.

Key point

Nucleophilic addition to carbonyls

Common mistake

thinking ketones are more reactive than aldehydes.

Memory tip

aldehydes are less crowded and more electrophilic → faster addition.
