(a) Differences in physical properties:
(i) Smell: Ethanol has a pleasant smell whereas ethaoci has a pungent smell (like that of vinegar).
(ii) Taste. Ethanol has a burning taste whereas ethanoci acid has a sour taste.
(iii) Boiling points: The boiling point of ethanol is low (being only 78^(@)C ) whereas that of ethanoic acid is comparatively high (being 118^(@)C).
(b) Differences in chemical properties:
(i) Action on litmus: Ehtanol has no action on any litmus (so it is a neutral compound) but ethanoic acid turns blue litmus to red (so it is an acidic compound).
(ii) Action on sodium hydrogencarbon. Ethanol has no reaction with sodium hydrogencarbonate but ethanoic acid gives brisk effervescence of carbon dioxide with sodium hydrogencarbonate.
