निम्नलिखित में से कौन-सा कथन सही नहीं है ?

A \(C _{2}\) अणु में दो समभ्रंश \(\pi\) आण्विक कक्षकों में चार इलेक्ट्रॉन होते हैं।
B \(H _{2}^{+}\)आयन में एक इलेक्ट्रॉन होता है।
C \(O _{2}^{+}\)आयन प्रतिचुंबकीय होता है।
D \(O _{2}^{+}, O _{2}, O _{2}^{-}\)और \(O _{2}^{2-}\) के आबंध क्रम क्रमशः \(2.5,2,1.5\) और \(1\) हैं।

Verified Solution

Answer & Solution

Correct Answer

(C) \(O _{2}^{+}\)आयन प्रतिचुंबकीय होता है।

Step-by-step Solution

Detailed explanation

\(O _{2}^{+}\)ion is having \(15\) electrons, so it contain one unpaired electron. Hence it is paramagnetic in nature.

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.
