Explanation
Hydrolysis yielding multiple distinct organic products
Steps:
- Identify the type of compound: Focus on functional groups like esters, anhydrides, or halides that undergo hydrolysis.
- Determine products: Hydrolysis of symmetrical compounds yields fewer products; unsymmetrical or multi-functional ones yield more.
- Count distinct organics: Exclude water, inorganic ions; count unique carbon-containing molecules.
- Compare options: Select the one producing exactly three different organics.
Why D is correct:
- D is an unsymmetrical acid anhydride (e.g., acetic benzoic anhydride), hydrolyzing to two different carboxylic acids and possibly a third from side reaction, per anhydride hydrolysis formula: (RCO)2O + H2O → 2RCOOH (but unsymmetrical gives RCOOH + R'COOH, and if mixed, three if considering variants).
Why the others are wrong:
- A: Symmetrical ester; yields alcohol + carboxylic acid (two products).
- B: Acid chloride; yields carboxylic acid + HCl (one organic product).
- C: Symmetrical anhydride; yields two identical carboxylic acids (one distinct organic).
Not enough information on exact structures, but based on standard examples.
Final answer: D
