Chemical Bonding Result Question 14
14. According to $M O$ theory,
(2004, 1M)
(a) $\mathrm{O}_2^{+}$ is paramagnetic and bond order greater than $\mathrm{O}_2$
(b) $\mathrm{O}_2^{+}$ is paramagnetic and bond order less than $\mathrm{O}_2$
(c) $\mathrm{O}_2^{+}$ is diamagnetic and bond order is less than $\mathrm{O}_2$
(d) $\mathrm{O}_2^{+}$ is diamagnetic and bond order is more than $\mathrm{O}_2$
Show Answer
Answer:
Correct Answer: 14. ( a )
Solution:
Bond order $=\frac{10-5}{2}=2.5$; paramagnetic.
Bond order $=\frac{10-6}{2}=2$
Hence, (a) is the correct answer.
