1.	Assertion . H_(2)molecule is more stable than HeH molecule. Reason . The antibonding elelctron in the molecule destabilises is .
Answer» If both assertion and reason are CORRECT, and reason is the correct explanation of the assertion. If both assertion and reason are correct , but reason is not the correct explanation of the assertion. If assertion is correct, but reason is incorrect . If both assertion and reason are incorrect. Solution :Correctexplanation . `H_(2)` molecular is more stable than HEH because bond order of `H_(2)` = 1 and that of Heh ` = (1)/(2)`(Higher the bond order , MOREIS the stability).
