Answer 2

1. Ethanol has sweet odour whileethanoic acid has pungent odour.Ethanol does not react with sodium bicarbonate (NaHCO₃) but ethanoic acid reacts with sodium bicarbonate (NaHCO₃) releasing CO2 gas. Ethanoldoes not change the colour of blue litmus paper while ethanoic acidchange the colour of blue litmus to red.

2. Most common difference is Cooking Oil remains liquid at low temperature around 10–15C while Butter turns into fat. Butter is dairy product containing high amount of saturated fatty acids while Cooking oil generally contains majority of unsaturated fatty acid. ...Cooking oil contains no water (less than 0.5%).
