Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Question Explanation:

The question asks the colour developed when ethyl alcohol is treated with base during the Victor Meyer test, which is used to distinguish 1°, 2°, and 3° alcohols.

Concept :

This question is based on Victor Meyer test, Classification of alcohols.

Solution : Ethyl alcohol (C₂H₅OH) is a primary (1°) alcohol.

In the Victor Meyer test:

1° alcohol → converted to nitroalkane → on treatment with base gives blood-red colour.

2° alcohol → blue colour.

3° alcohol → no colour.

Since ethyl alcohol is primary, it gives a blood-red colour with base.

Final answer : Option (1)
