Sigma and Pi Covalent Bonds

What is a sigma bond?

• A bond formed by the linear or co-axial overlapping of atomic orbitals

• A bond formed by the parallel overlapping of atomic orbitals

• A bond formed by the perpendicular overlapping of atomic orbitals

• A bond formed by the diagonal overlapping of atomic orbitals

What is a pi bond?

• A bond formed by the linear overlapping of atomic orbitals

• A bond formed by the parallel or lateral overlapping of atomic orbitals
