Question: Which of the following is/are correct for nitric oxide?...

Which of the following is/are correct for nitric oxide?

A

It is an odd electron species

B

It's bond order is 2.5

C

It is neutral oxide

D

Octet rule is not satisfied

Answer

All options (1, 2, 3, and 4) are correct.

Explanation

Solution

  1. Odd-electron species: NO has 11 electrons, which makes it a radical (an odd number of electrons).

  2. Bond order: From molecular orbital theory, the bond order of NO is calculated as 2.5.

  3. Neutral oxide: NO is a neutral molecule (not an ion) consisting of nitrogen and oxygen.

  4. Octet rule: With 11 electrons, NO cannot satisfy the octet rule for both atoms.
