નીચેનામાંથી કયા આયનીકરણની પ્રક્રિયામાં બંધ ઊર્જા વધે છે અને ચુંબકીય વર્તણૂક અનુચુંબકીયથી પ્રતિચુંબકીયમાં બદલાય છે.

A \(O_2 \rightarrow O_2^+\)
B \(C_2 \rightarrow C_2^+\)
C \(NO \rightarrow NO^+\)
D \(N_2 \rightarrow N_2^+\)

Verified Solution

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.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
