In which of the following transformations, the bond order has increased and the magnetic behaviour has changed?
Options
- AC 2 + → C 2
- BN O + → N O
- CO 2 → O 2 +
- DN 2 → N 2 +
Correct answer
A. C 2 + → C 2
Step-by-step solution
On the basis of molecular orbital theory the value of bond order and magnetic nature can be given as C 2 + B O = 1.5 P a r a m a g n e t i c → C 2 B O = 2 D i a m a g n e t i c N O + B O = 3 D i a m a g n e t i c → N O B O = 2.5 P a r a m a g n e t i c O 2 B O = 2 P a r a m a g n e t i c → O 2 + B O = 2.5 P a r a m a g n e t i c N 2 B O = 3 D i a m a g n e t i c → N 2 + B O = 2.5 P a r a m a g n e t i c
