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 |
