Q16 / 75 · JEE Main 2020 (07 Jan Shift 1) · Chemistry

Consider the following reaction:

The product $' X^{'}$ is used:

A
in protein estimation as an alternative to ninhydrin
Correct answer
B
in acid base titration as an indicator
C
as food grade colourant
D
in laboratory test for phenols

Solution

Methyl orange is used as indicator in acid base titration.

Azo coupling is the most widely used industrial reaction in the production of dyes, lakes and pigments. Aromatic diazonium ions acts as electrophiles in coupling reactions with activated aromatics such as anilines or phenols.

Hence, the correct answer is option: 'B'.
