As we have learnt,

Nitric oxide -

NO (+2), colourless

- wherein

N= O

Bond Order of NO is 2.5

1s \Rightarrow \sigma1s^2, \sigma^* 1s^2, \sigma2s^2, \sigma^*2s^2, \sigma2pz^2, \overset{\uparrow\downarrow}{\pi} 2px = \overset{\uparrow\downarrow}{\pi} 2py, \overset{\uparrow}{\pi^*} 2px = {\pi^*} 2py

Bond Order = \frac{10-5}{2} = 2.5
