Activity 4.8 NCERT Class 10 Science, Carbon, and its Compounds

Brief procedure:

Activity 4.8 asks us to react glacial acetic acid with ethanol in the presence of acid and observe the smell.

Observation:

We observe a fruity smell from the solution.

Explanation:

Ethanol reacts with acetic acid in the presence of concentrated sulphuric acid and forms ester. Ester has a characteristic fruity or pleasant smell, which we can detect by the smell.

This is a reversible reaction, ethyl acetate produced is dilute after formation to avoid the backward reaction. Addition of bases like sodium hydroxide also reverses the reaction.

Next: Activity 4.9 – Reaction of ethanoic acid with carbonates.
