A Levels Chemistry (9701)•9701/13/O/N/19

Explanation
Hydrolysis of multifunctional compounds yielding multiple distinct products
Steps:
- Identify compounds with multiple hydrolyzable groups that can break independently.
- Determine products from each group: e.g., esters yield carboxylic acid and alcohol.
- Count unique organic products; three requires at least two different groups producing distinct molecules.
- Select option where hydrolysis fragments yield exactly three different organics.
Why D is correct:
- D is an unsymmetrical diester like ROOC-CH2-COOR', hydrolyzing to HOOC-CH2-COOH, ROH, and R'OH—three distinct products per standard ester hydrolysis (R ≠ R').
Why the others are wrong:
- A: Symmetric diester yields two products (diacid + alcohol).
- B: Monoester yields two products (acid + alcohol).
- C: Anhydride yields two carboxylic acids.
Final answer: D
