Question

Which of the following properties are not shown by NO?

  • It is diamagnetic in gaseous state

  • It is a neutral oxide

  • It combines with oxygen to form nitrogen dioxide

  • Its bond order 2.5

Answer

A.

It is diamagnetic in gaseous state

D.

Its bond order 2.5

NO is paramagnetic in the gaseous state because, in a gaseous state, It has one unpaired electron.
Total number of electron present = 7+8 = 15e-
Hence, there must be the presence of unpaired electron in a gaseous state while in a liquid state, it dimerises due to the unpaired electron.
