Answer:

Acetic acid being acidic reacts with carbonates or bicarbonates to give brisk effervescence due to the evolution of carbondioxide whereas ethanol does not react.

CH3COOH+Na2CO3→CH3COONa+H2O+CO2↑

(ii) Fehling's solution test is used to distinguish between acetaldehyde and benzaldehyde as:

acetaldehyde gives red precipitate of cuprous oxide while benzaldehyde does not.

CH3CHO+5OH−+2Cu2+→CH3COO−+Cu2O↓+3H2
