Physical properties

Ethanol:- 1. Ethanol is a colorless liquids having pleasant smell.

2.Boiling point of ethanol is 78℃ (351 K).

3.Melting point of ethanol is 156 K.

4.It is non conductor of electricity because it does not contain ions.

5.It is neutral to litmus.

Ethanol acid:-

1.Ethanoic acid is a colorless vicious liquids but has a pungent and irritating smell of vinegar.

2.Boiling point of ethanol acid is 118℃(391 K).

3.Melting point of ethanol acid is 290K.

4.It is a good conductor of electricity because it contains ion.

5.It is acidic in litmus.

Chemical properties

Ethanol:-

1.Ethanol doesn't react with metal carbonate.

2.Ethanol doesn't react with NaOH.

3.Ethanol is oxidized to give ethanoic acid in presence of acidified KMnO4.

Ethanoic acid :-

1.Ethanoic acid react with metal carbonate to form salt ,CO2 and H2O.

2.Ethanoi acid react with NaOH to form sodium ethanoate and water.

3.In ethanoic acid no reaction take place on the presence of acidified KMnO4.

answer:

Ethanol is a liquid at room temperature with a pleasant odour while ethanoic acid has vinegar-like smell. The melting point of ethanoic acid is 17°C. ... Ethanoic acid reacts with metal carbonates and metal hydrogencarbonates to form salt, water, and carbon dioxide gas while ethanol does not react with them.

good evening danish

Explanation:

whats up

Ethanol and Ethanoic acid be differentiated on the basis of their following properties:

→ Ethanol is a liquid at room temperature with a pleasant smell. Ethanoic acid has a melting point of 17°C. Since it is below the room temperature so, it freezes during winter. Moreover, ethanoic acid has a smell like vinegar.

→ Ethanol does not react with metal carbonates while, ethanoic acid reacts with metal carbonates to form salt, water and carbon dioxide. For example,

2CH3COOH + Na2CO3 → 2CH3COONa + CO2 + H2O

→ Ethanol does not react with NaOH while ethanoic acid reacts with NaOH to form sodium ethanoate and water. For example,

CH3COOH + NaOH → CH3COONa + H2O→ Ethanol is oxidized to give ethanoic acid in presence of acidified KMnO4while, no reaction takes place with ethanoic acid in presence of acidified KMnO4.

Ethanol has a pleasant smell whereas ethanoic acid has the smell of vinegar. (ii) Ethanol has a burning taste whereas ethanoic acid has a sour taste.

Explanation:

In a physical change, the molecules are reorganized while their real composition remains same. In a chemical change, the atomconfiguration of a substance completely changes and a new substance is molded. Some instance of physical alterationare freezing of water, melting of wax, boiling of water, etc.

Ethanol has a pleasant smell whereas ethanoic acid has the smell of vinegar.

(ii) Ethanol has a burning taste whereas ethanoic acid has a sour taste.

(iii)The boiling point of ethanol is low (351 K) whereas that of ethanoic acid is comparatively high (391 K).

(b) Differences in chemical properties :

(i) Ethanol has no action on any litmus paper but ethanoic acid turns blue litmus to red.

(ii) Ethanol has no reaction with sodium hydrogencarbonate but ethanoic acid gives brisk effervescence of carbon dioxide with sodium hydrogencarbonate.
