The compound which does not show paramagnetism is.... answer this with explaination

Please accept my answer Dear 🙏

See this No dimer

Cu²+ is d⁹ configuration. it has unpaired eletron. NO & NO2 too have unpaired eletron.

The shape of [Cu(NH3​)4​]2+ is square planer Cu2+ has electronic configuration 3d94s04p0. The electronic rearrange to 3d84s04p1 giving dsp2 hybridisation i.e square planer structur...

NO has an odd number of electrons and, therefore, must be paramagnetic. e. CO is diamagnetic because all of its electrons are paired.

Paramagnetism is due to the presence of at least one unpaired electron in the molecule. ... Though NO2 is paramagnetic, its dimer, N2O4, is diamagnetic

Check unpaired eletron Shristy. Compound which doesn't have unpaired eletron will not show paramagnetism.
