Chemistry Question on Chemical bonding and molecular structure
Bond order and magnetic moment of CO+ is
A
2.5 and paramagnetic moment
B
3.5 and diamagnetic moment
C
3.5 and paramagentic moment
D
2.5 and diamagnetic moment
Answer
3.5 and paramagentic moment
Explanation
Solution
HOMO of CO is a ?-non-bonding orbital with a fair degree of antibonding character. Loss of one electron lowers the anti-bonding electron number.
