Expert Answer:

Option (c)

NO2 → N2O4

The above reaction is a dimerisation reaction.

 

NO2 is paramagnetic since in NO2 we have:

One N=O

One N- O

And one unpaired electron on the N atom.

After the dimerisation reaction, N2O4 formed is diamagnetic since the unpaired electron gets paired.

Hence there is decrease in paramagnetism.
