Question

Which of the following is the correct comparison of the stability of the molecules?

• A. CN\(^{+}\)<O\(_2^{+}\)
• B. CN = N\(_2\)
• C. N\(_2\)<O\(_2\)
• D. H\(_2^{+}\)>He\(_2^{+}\)

Hint:

In molecular orbital theory, H\(_2^{+}\) has a higher bond order than He\(_2^{+}\), making it more stable.

Answer 1

The Correct Option is D

Step 1: Understand the molecular comparison.
Comparing the stability of diatomic molecules or ions, H\(_2^{+}\) is more stable than He\(_2^{+}\) due to the higher bond order in H\(_2^{+}\).
Step 2: Conclusion.
Thus, the correct answer is (D) H\(_2^{+}\)>He\(_2^{+}\).
Final Answer: \[ \boxed{D} \]
