Since, NO has an odd electron so it is paramagnetic but its colourless? why ? while, NO2 has odd electron too and it is paramagnetic and a browncolour gas.

Dear Student,
NO is generally paramagnetic yet it tends to frame diamers. In diamerisation, two particles with odd electrons consolidate to frame a steady structure. Since NO typically exists as a diamer, it ends up noticeably diamagnetic and thus is drab. 
Cheers!!

Vikas, brother
NO doesnt undergoes dimerization, its NOwhich form N2O4 at dimer stage and lose its odd electron so colourless and diamagnetic whicle its monomer NO2 have odd electron so paramag and brown coloured. My question is about NO not about NO2.
