Question

How two enantiomers of the asymmetric Ketone or Aldehyde is formed in nucleophilic addition reaction? ​

Answer 1

Answer:

I Hope it will work.

Explanation:

Step 1 is addition of a nucleophile to the electrophilic carbonyl carbon. This forms C–Nu and breaks C–O (π), resulting in a negatively charged oxygen. Step 2 is addition of an acid (“protonation”), which results in formation of the O–H bond.
