Sigma Bond

Sigma Bond is the strongest bond and can be found in alkanes, alkenes, and alkynes. If we look at the Sigma Bond definition, this is the bond that is formed by face-to-face overlapping of the atomic orbitals. Sigma Bonds can rotate freely and independently with less emission of energy, which makes them more stable. Due to this stability of the Sigma Bond, the bond length, bond energy, and other factors become easier to predict.
