$\mathrm{OF}$ and $\mathrm{F}_2$ can be compared in terms of

• A

  $\mathrm{OF}$ is paramagnetic while $\mathrm{F}_2$ is diamagnetic
• B

  OF is more stable towards dissociation into atoms
• Correct answer
  C

  Both (a) and (b) are correct
• D

  None of the above is correct

Solution

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

Hence, the correct answer is option: 'C'.
