Incorrect statement regarding NO2 molecule
The incorrect statement regarding NO2 molecule is:
c) It is deeply coloured in dimeric form
Explanation
NO2 molecule has the following characteristics:
- Electronic configuration: It has an odd number of electrons (17), one of which is unpaired in one of the sp2-hybridized orbitals.
- Colour: It is coloured due to the presence of an unpaired electron, which causes the molecule to absorb visible light in the blue-green region of the spectrum. Hence, it appears brown in the gaseous state.
- Dimeric form: At low temperatures, NO2 molecules combine to form N2O4, a dimeric form. The colour of N2O4 is pale yellow, and it is less reactive than NO2.
- Magnetic behavior: NO2 is paramagnetic due to the presence of an unpaired electron, whereas N2O4 is diamagnetic since all electrons are paired.
Therefore, option c) is incorrect because N2O4 is pale yellow, not deeply coloured.
