Q.
Given below are two statements:

Statement I: Sulphanilic acid gives esterification test for carboxyl group.

Statement II: Sulphanilic acid gives red colour in Lassaigne’s test for extra element detection.

In the light of the above statements, choose the correct answer from the options given below: [2023]

1 Both Statement I and Statement II are correct

2 Both Statement I and Statement II are incorrect

3 Statement I is incorrect but Statement II is correct

4 Statement I is correct but Statement II is incorrect

Ans.
(3)

Sulphanilic acid has no –COOH group hence no esterification test for carboxyl group. But it has sulpher and nitrogen atom hence gives red colour in Lassigne’s test for extra element detection.

Solution

1 Both Statement I and Statement II are correct

2 Both Statement I and Statement II are incorrect

3 Statement I is incorrect but Statement II is correct

4 Statement I is correct but Statement II is incorrect

Ans.
(3)

Sulphanilic acid has no –COOH group hence no esterification test for carboxyl group. But it has sulpher and nitrogen atom hence gives red colour in Lassigne’s test for extra element detection.
