Question

Of the following, which has three electron bond in its structure ?

• A. Nitrous oxide
• B. Nitric oxide
• C. Dinitrogen trioxide
• D. Nitrogen pentoxide

Answer 1

The correct option is B Nitric oxide

Accordingly to the structure given above, three electron bond can only be present in either Nitric Oxide or Nitrogen Dioxide. But it is a fact that Nitrogen Dioxide $\left(N{O}_2\right)$ exist in dimeric form with one $N-N$ bond whereas $NO$ exist in monomeric form.

So, Nitric Oxide has one 3-electron bond in i's structure.

Hence, Option "B" is the correct answer.
