NEET · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
In which of the following ionization processes the bond energy increases and the magnetic behaviour changes from paramagnetic to diamagnetic.
- A \(O_2 \rightarrow O_2^+\)
- B \(C_2 \rightarrow C_2^+\)
- C \(NO \rightarrow NO^+\)
- D \(N_2 \rightarrow N_2^+\)
Answer & Solution
Correct Answer
(C) \(NO \rightarrow NO^+\)
Step-by-step Solution
Detailed explanation
In \(C_{2}-C_{2}^{+}\) electrons is removed from bonding molecular orbital so bond order decreases. In \(N O \rightarrow N O^{+}\) electrons is removed from anti bonding molecular orbital so bond order increases and nature changes from paramagnetic to diamagnetic.
