How many σ and π bonds are present in the compound given below:

Answer»

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
