Assertion: Magnetic susceptibility of diamagnetic substance is small negative.
Reason: Diamagnetic substance have unpaired electron.

View answer and explanation

Correct option: C

If Assertion is True but the Reason is False

Option C (If Assertion is True but the Reason is False) is correct because diamagnetic substances have a small negative magnetic susceptibility, but this is due to paired electrons, not unpaired electrons.
