sigma and pi bonds

[Baria Alaswad 2E]

Can you explain how sigma and pi bonds contribute to the structural stability and reactivity of molecules in both organic and inorganic compounds?

[Kailey Emmons 2G]

Sigma bonds are stronger than pi bonds and thus contribute more to structural stability. Because of this, molecules with sigma bonds are also generally less reactive than molecules with pi bonds, while molecules with pi bonds are more reactive.

Hi,

so sigma and pi bonds contribute to the stability of a molecule or its molecular structure as sigma bonds directly connect elements together and are much stringer, whereas pi bonds must be accompanied by a sigma bond and are only in multiple bonds, not single bonds, hence electrons are not led back by the nucleus as strongly and increase reactivity.

Sigma bonds are stronger and contribute more to stability. However, when a pi bond is added, molecules are no longer allowed to rotate, while they are with a sigma bond.
