Structure of \(M\) is,
- A \(\mathrm{Ph}-\mathrm{C} \equiv \mathrm{CH}\)
- B \(\mathrm{Ph}-\mathrm{C} \equiv \mathrm{C}-\mathrm{CH}_3\)
- C \(\mathrm{H}_3 \mathrm{C}-\mathrm{C} \equiv \mathrm{CH}\)
- D \(\mathrm{H}_3 \mathrm{C}-\mathrm{C} \equiv \mathrm{C}-\mathrm{CH}_3\)
Answer & Solution
Correct Answer
(A) \(\mathrm{Ph}-\mathrm{C} \equiv \mathrm{CH}\)
Step-by-step Solution
Detailed explanation
Hint : Benzaldehyde \((\mathrm{O})\) gives Cinnamic acid \((\mathrm{Ph}-\mathrm{CH}=\mathrm{CH}-\mathrm{COOH})\) on reaction with \(\left(\mathrm{CH}_3 \mathrm{CO}\right)_2 \mathrm{O}\) and \(\mathrm{CH}_3 \mathrm{COONa}\) known as Perkin's condensation
