Question

A molecule \( (X) \) with the following structure under mild acidic conditions is hydrolyzed to produce \( (Y) \) and \( (Z) \). Identify the correct statements about \( (Y) \) and \( (Z) \).}

• A. Both \( (Y) \) and \( (Z) \) have the same molar mass.
• B. \( (Y) \) and \( (Z) \) can be distinguished from each other by NaHCO\(_3\).
• C. \( (Y) \) and \( (Z) \) react with HCN with the same rates.
• D. \( (Y) \) and \( (Z) \) undergo addition reaction with 2,4-DNP.

Answer 1

The Correct Option is B

Step 1: Analyzing the hydrolysis reaction.
Given the structure of molecule \( (X) \), hydrolysis under mild acidic conditions will produce two compounds: \( (Y) \) and \( (Z) \). These two products are likely to be different forms of a functional group (e.g., an ester or amide) reacting under the same conditions.
Step 2: Identifying the properties of \( (Y) \) and \( (Z) \).
- (A) Both \( (Y) \) and \( (Z) \) having the same molar mass: This is unlikely as their functional groups and molecular structures could differ, resulting in different molar masses.
- (B) \( (Y) \) and \( (Z) \) can be distinguished from each other by NaHCO\(_3\): This is correct. Different functional groups such as acids and esters/amides will show different reactivity with NaHCO\(_3\).
- (C) \( (Y) \) and \( (Z) \) react with HCN with the same rates: This is likely correct, as both \( (Y) \) and \( (Z) \) are functionalized molecules with similar reactivity.
- (D) \( (Y) \) and \( (Z) \) undergo addition reaction with 2,4-DNP: This is also correct, as both \( (Y) \) and \( (Z) \) might be carbonyl compounds and thus react with 2,4-DNP.
Step 3: Conclusion.
The correct answers are \( (B) \) and \( (C) \) since they correctly describe the distinguishing properties of the compounds formed after hydrolysis.
Final Answer: (B) and (C) Only
