JEE MAIN - Chemistry (2022 - 25th June Morning Shift - No. 1)
Bonding in which of the following diatomic molecule(s) become(s) stronger, on the basis of MO Theory, by removal of an electron?
(A) NO
(B) N2
(C) O2
(D) C2
(E) B2
Choose the most appropriate answer from the options given below :
(A), (B), (C) only
(B), (C), (E) only
(A), (C) only
(D) only
Explanation
If an electron is removed from the anti-bonding
orbital, then it will tend to increase the bond order.
The HOMO in NO and O2 is antibonding molecular
orbital .
Hence, in NO and O2 bond order will increase on loss of electron.
Hence, in NO and O2 bond order will increase on loss of electron.
