Assertion: Fluorine molecule has bond order one.

Reason: The number of electrons in the antibonding molecular orbitals is two less than that in bonding molecular orbitals.

(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

(c) If the Assertion is correct but Reason is incorrect.

(d) If both the Assertion and Reason are incorrect.

(e) If the Assertion is incorrect but the Reason is correct.

(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Explanation:

MO electronic configuration of F2 molecule.

Thus there are 10 electrons in bonding orbitals and 8 electrons in antibonding orbitals. Thus, reason is true and it is also the correct explanation of assertion because

Bond order = Nb - Na/2

= 10 - 8/ 2 = 1
