Select the correct statement(s) about NO2.
  • a)
    It is paramagnetic in nature
  • b)
    It forms dimer and paramagnetic is lost
  • c)
    NO2 and dimer formed have sp2-hybridised N-atom
  • d)
    Brown colour of NO2 fades and (N— N) bond length is greater than normal (N— N) bond length
Correct answer is option 'A,B,C,D'. Can you explain this answer?

Due to unpaired electron paramagnetic, N-atom in NO2 is electron deficie nt thus, to complete octet, dimer is formed.

In N2O4 formation, each N-atom gets charge. Dipole-dipole repulsion increases (N— N) bond length which is larger than (N— N)covalent bond.

Thus, (a), (b), (c) and (d) are correct.

NO2 is paramagnetic since it is having odd number of electrons with lone pair.
It forms dimer in liquid or solid state to attain stability.
The hybridisation state becomes sp2.
The characteristic brown colour of monomolecular NO2 is lost due to dimer formation. Bond lengths is also affected due to dimerisation.
check the dimerisation topic.
