The nitrogen containing compound produced in the reaction of H N O 3 with P 4 O 10

Options

  1. ACan also be prepared by reaction of P 4 and H N O 3
  2. BIs diamagnetic
  3. CContains one N-N bond
  4. DReacts with Na metal producing a brown gas

Correct answer

B. Is diamagnetic

Step-by-step solution

P 4 O 10 + 4 H N O 3 → d e h y d r a t i o n H N O 3 4 H P O 3 + 2 N 2 O 5 r e q u i r e d p r o d u c t A] P 4 + 20 H N O 3 → 4 H 3 P O 4 + 20 N O 2 ↑ + 4 H 2 O B] N 2 O 5 is diamagnetic in nature C] N 2 O 5 contains one N - O - N bond not N - N bond.
