Which one of the following properties is not shown by NO?

Answer»

It is diamangetic in gaseous STATE.
It is a NEUTRAL OXIDE.
It combines with OXYGEN to form nitrogen dioxide.
Its bond order is 2.5.

Solution :NO is paramagnetic in gaseous state because it has one unpaired electron. However, it dimerises at low temperature to become diamagnetic. It combines with `O_(2)` to form `NO_(2)` and is neutral oxide and has bond order of 2.5.
