Assertion : Sulphur present in an organic compound can be estimated quantitatively by Carius method.
Resaon : Sulphur is separated easily from other atoms in the molecule and gets precipitated as light yellow solid.

A

If both (A) and (R ) are correct and (R ) is the correct explanation of (A)

B

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

C

If (A) is correct, but (R ) is incorrect

D

If both (A) and (R ) are incorrect

Text Solution

Verified by Experts

The correct Answer is:
C
Sulphur is oxidised to `H_(2)SO_(4)` in Carius method and then estimated as barium sulphate.
