Given below are two statements :
Statement I : Nitrogen forms oxides with +1 to +5 oxidation states due to the formation of $\mathrm{p} \pi-\mathrm{p} \pi$ bond with oxygen.
Statement II : Nitrogen does not form halides with +5 oxidation state due to the absence of d-orbital in it.
In the light of given statements, choose the correct answer from the options given below.

• A

  Statement I is true but Statement II is false
• B

  Both Statement I and Statement II are false
• C

  Statement I is false but Statement II is true
• Correct answer
  D

  Both Statement I and Statement II are true

Solution

In oxide of nitrogen it can achieve +5 oxidation state because it can form $\mathrm{p} \pi-\mathrm{p} \pi$ bond with oxygen e.g. $\mathrm{N}_2 \mathrm{O}_5$

Nitrogen cannot form halide in +5 oxidation state because it does not contain d-orbital.
e.g. $\mathrm{NX}_5$ does not exist
$\mathrm{X}=\text { halide }$

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