Chemistry - Carbonyl compounds Question with Solution | TestHub
Options:
Answer:
Solution:
Question Explanation:
The question asks for the major product formed when benzaldehyde (Ph–CHO) reacts with acetic anhydride in the presence of acetate ion (MeCOO- ) and heat.
Concept:
This question is based on Perkin Reaction, Aldehyde Condensation, α,β-Unsaturated Carboxylic Acid Formation.
Solution:
Benzaldehyde reacts with acetic anhydride in the presence of acetate ion (MeCOO- ) and heat.
This is a classic Perkin reaction, where an aromatic aldehyde condenses with an acid anhydride.
The reaction forms an α,β-unsaturated carboxylic acid after hydrolysis.
In this case, the product is cinnamic acid (Ph–CH=CH–COOH).
Other options correspond to aldehyde or hydrocarbon products, which are not formed under Perkin reaction conditions.
Final Answer : Option (A)
