JEE Main 2026 Chemistry question
A molecule (X) with structure CH₂=CH−CH₂−O−C(CH₃)=CH₂ (allyl isopropenyl ether) under mild acidic condition is hydrolysed to produce (Y) and (Z). Identify the correct statements about (Y) and (Z). A. Both (Y) and (Z) have same molar mass. B. (Y) and (Z) can be distinguished from each other by NaHCO₃. 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:
Solution
Acid hydrolysis of this enol ether cleaves it to allyl alcohol (Y, C₃H₆O, M = 58) and acetone (Z, C₃H₆O, M = 58), so A is true. As per the official key, D is also taken as true; however, since Y is a simple alcohol with no carbonyl group, its reaction
