JEE Main 2025 Jan 28 Shift 1, Chemistry Q12: Properties and Important Reactions of Aldehydes & Ketones
JEE Main2025Jan 28, Shift 1Chemistry
Q.
Both acetaldehyde and acetone (individually) undergo which of the following reactions?
A. Iodoform Reaction
B. Cannizaro Reaction
C. Aldol condensation
D. Tollen's Test
E. Clemmensen Reduction
Choose the correct answer from the options given below :
- A
A, B and D only
- B
A, C and E only
- C
C and E only
- D
B, C and D only
Solution
Check each test against both carbonyls:
| Reaction | Acetaldehyde (CHCHO) | Acetone (CHCOCH) |
|---|---|---|
| Iodoform | Yes (methyl ketone-like) | Yes |
| Cannizzaro | No (-H present) | No (-H present) |
| Aldol | Yes | Yes |
| Tollens' | Yes | No (ketone) |
| Clemmensen | Yes | Yes |
Both carbonyls give a positive iodoform test, aldol, and Clemmensen reduction.
A, C and E only.
