Chemistry Question on Chemical bonding and molecular structure
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
(A), (B), (C) only
B
(B), (C), (E) only
C
(A), (C) only
D
(D) only
Answer
(A), (C) only
Explanation
Solution
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.
So, the correct option is (C).
