OF and F_2 can be compared in terms of

OF\mathrm{OF} and F2\mathrm{F}_2 can be compared in terms ofOF and F_2 can be compared in terms of

Options

  1. AOF\mathrm{OF} is paramagnetic while F2\mathrm{F}_2 is diamagnetic
  2. BOF is more stable towards dissociation into atoms
  3. CBoth (a) and (b) are correct
  4. DNone of the above is correct

Correct answer

C. Both (a) and (b) are correct

Step-by-step solution

OF and F_2 can be compared in terms of
This is one unpaired electron in (O−F)(\mathrm{O}-\mathrm{F}), hence paramagnetic, thus (a) is correct. As bond order of O−F>F−F\mathrm{O}-\mathrm{F} > \mathrm{F}-\mathrm{F} thus, bond energy of O−F>F−F\mathrm{O}-\mathrm{F} > \mathrm{F}-\mathrm{F}. Hence, (a) and (b) both are correct.
