Give one chemical test for each to distinguish between the following pairs of compound:
Acetaldehyde and benzaldehyde
Answer
Answer
AIFehling's test test: reagent: Fehling's solution, heat; positive: Acetaldehyde; observation: Red-brown precipitate of Cu2O; other: Benzaldehyde gives no precipitate
Fehling's test distinguishes them.
| Test | Acetaldehyde | Benzaldehyde |
| Fehling's solution, heat | Red-brown precipitate of $\mathrm{Cu_2O}$ | No precipitate |
