Which property is NOT exhibited by nitric oxide (NO)?

1. It reacts with oxygen to give nitrogen dioxide.
2. Its bond order is 2.5.
3. In the gas phase it is diamagnetic.
4. It is a neutral oxide.

Correct answer: In the gas phase it is diamagnetic.

Solution

NO has 15 electrons, leaving one unpaired electron in a pi*2p orbital, so it is paramagnetic in the gas phase, not diamagnetic. It does react with O2 to form NO2, has bond order 2.5, and is a neutral oxide.
