Assertion(A) : Aniline hydrogen sulphate...

Assertion(A) : Aniline hydrogen sulphate on heating froms a mixture of o- and p-amineo- sulphonic acid .
Reason (R ) : The suphonic acid is ` overline e withdrawing .

A

If both (A) and (R ) ar true, and (R ) is the correct explanation of (A).

B

If both (A) and (R ) are true , and (R ) is not the correct explanation of (A).

C

If (A) is true , but (R ) is false .

D

If both (A) and (R ) are false .

Text Solution

Verified by Experts

The correct Answer is:
B

Correct exphanation :
Aniline hydrogen sulp-hate on heating decomposes to aniline and ` H_2SO_4`. Sulphonation fo aniline with ` H_2SO_4` takes place (SE resaction ) at o- and p-positions , since `(-NH_2)` group is o- p-directing .
