When saturated sodium bisulfite is added to various carbonyl compounds, which of these aromatic ketones fails to form a white crystalline precipitate?
Q1. When saturated sodium bisulfite is added to various carbonyl compounds, which of these aromatic ketones fails to form a white crystalline precipitate?
Answer: Acetophenone
Explanation: Bisulfite addition involves a large nucleophile, so steric hindrance prevents most ketones from reacting. Aldehydes react easily due to less crowding.
