A. Both (Y) and (Z) have same molar mass.
B. (Y) and (Z) can be distinguished from each other by \(NaHCO_3\).
C. (Y) and (Z) react with HCN with same rates.
D. (Y) and (Z) undergo addition reaction with \(2,4\)-DNP.
Choose the correct answer from the options given below:
- A A, B and C Only
- B B and C Only
- C C and D Only
- D A and D Only
Answer & Solution
Correct Answer
(D) A and D Only
Step-by-step Solution
Detailed explanation
Molecule \((X)\) is an ether with two enol ether functional groups attached to the central oxygen atom. On mild acidic hydrolysis, an enol ether cleaves to give a carbonyl compound and an alcohol. The \(1\)-propenyl side \((CH_3-CH=CH-O-)\) hydrolyses to propanal,…
