Bonds

[Nicole Jakiel 4F]

How do we know which type of bond is present? In other words, how do we know when there is a pi bond or when there is a sigma bond?

[Mahir_Hasan2C]

Whenever there is a single bond, it is just a sigma bond. Whenever it is a double bond, there is a sigma bond and a double bond. Whenever it is a triple bond, there is a sigma bond with 2 pi bonds.

There can be different types of bonds depending on the two atoms that are forming the molecule. For example when a metal and nonmetal are bonded it creates an ionic bond whereas when two nonmetals are bonded it creates a covalent bond. Pi and sigma bonds can apply to either of these and are usually talked about when there are multiple bonds in a molecule. The first bond formed is always a sigma bond and the ones following are pi bonds
