What simple test can you use to differentiate ethyl alcohol, ethyl acetate and acetic acid?

Answers

Answered by kuhu005

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↓+3H2O

I hope it will helpful to you give thanks to my answer nd follow me pliss
