Question

can sigma bond be formed without pie bond . explain . please help​

Answer 1

Explanation:

A pi bond can exist between two atoms that do not have a net sigma-bonding effect between them. ... In some cases of multiple bonds between two atoms, there is no net sigma-bonding at all, only pi bonds.

Then, it is a matter of counting the bonds in the correct Lewis structure according to the following simple rules: Every single covalent bond is a sigma bond. Every double covalent bond has both a sigma and a pi bond in it. Every triple covalent bond has a sigma and two pi bonds in it.
