Question

How many σ and π bonds are present in the compound given below: $H_{3}C - CH = CH - C \equiv N$

Answer 1

σ bond: The strongest type of covalent chemical bonds are sigma-bonds which are formed by head-on overlap between two atomic orbitals.

π bonds: Side to side overlapping of two atomic orbitals forms a pi-bonds which is a covalent bonds. Pi-bonds are easily broken.

A single sigma-bond and one or two pi-bonds are usually formed double or triple bonds.  

The number of sigma-bonds in the above chemical structure is 9.

And, the number of pi-bonds in the above chemical structure is 3.

Explanation: C-C sigma-bonds = 3

                      C-H sigma-bonds = 5

                      C-N sigma bonds = 1

                      C-C pi-bonds = 1

                       C-N pi-bonds = 2
