Question

How many pi bonds are in $CaC{N}_2$?

• A. 2
• B. 3
• C. 1
• D. 4

Answer 1

The correct option is A 2

A double bond consists of one sigma and one pi bond so it has $2$ $\pi$ bonds.

Structure of $CaC{N}_2$ is as follow: $\left[C{a}^{2+}\right]{[}^{-}N=C=N^{-}]$.

Thus it contains $2\pi$ bonds.
