Read the following statements regarding chemical reactivity of group 15 elements.
(i) Only compound of with +5 oxidation state is .
(ii) Intermediate oxidation states for both nitrogen and phosphorus disproportionate in both acid and alkali.
(iii) Nitrogen due to absence of d-orbitals in its valence shell cannot form -p bond as the heavier elements thus exists but does not exists.
(iv) is the strongest reducing agent amongst the hydrides of nitrogen family.
(v) is more acidic than .
Which of the following is the correct code for the statements above?

Which of the following is the correct code for the statements above?
View answer and explanation
Correct option: C
TFTTF
Option C (TFTTF) is correct because statements (i), (iii), and (iv) are true, while (ii) and (v) are false based on the chemical reactivity of group 15 elements.
