Question

Sample 'X' is a mixture of two liquids A and B. It is subjected to paper chromatography and gives the chromatogram P. When the same sample is subjected to heating, chromatogram Q is obtained. What do you infer from the two chromatograms?

• A. B is thermally unstable
• B. B has high chemical stability
• C. B is converted to A
• D. A is concerted to B

Answer 1

The correct option is A B is thermally unstable

When subjected to heating, position of B changes indicating that it is thermally unstable.
