Assertion: sp^(3) hybrid carbon atom is more electronegative than sp hybrid carbon atom. Reason: sp^(3) hybrid orbitals are more closer to the nucleus.

Answer»

If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false.
If both assertion and reason are false.

Solution :The greater s character of an orbital means it is more CLOSER to the nucleus and it is more electronegative. Hence, sp HYBRID CARBON ATOM is more electronegative.
