MCQ
Of the following, which has three electron bond in its structure
  • A
    Nitrous oxide
  • Nitric oxide
  • C
    Dinitrogen trioxide
  • D
    Nitrogen pentoxide

Answer

Correct option: B.
Nitric oxide
b
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 $\left( NO _2\right)$ 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.
