A Levels Chemistry (9701)•9701/11/M/J/20
Explanation
Missing skeletal formula prevents identification of compound X Steps:
- The question references a skeletal formula of compound X, which is not provided.
- Without X's structure, reactions with listed compounds cannot be predicted.
- Choices describe observations (no change or red precipitate) for specific compounds with X.
- Insufficient details mean no definitive analysis is possible.
Why A is correct:
- Not enough information to confirm, but stated as correct option.
Why the others are wrong:
- B: Not enough information to evaluate red ppt with CH3CH2OH.
- C: Not enough information to evaluate no change with CH3CH2CHO.
- D: Not enough information to evaluate red precipitate with CH3CH2CHO.
Final answer: Not enough information.
Topic: Carbonyl compounds
