The unhybridized p orbitals in each carbon atom of ethylene are perpendicular to the plane of the hybrid orbitals. What type of bond is formed between these unhybridized p orbitals?
Sigma bond
Pi bond
Covalent bond
Hydrogen bond
The overlap of hybrid orbitals or a hybrid orbital and a 1s orbtial from hydrogen creates the sigma bond framework of the ethylene molecule. However the unhybridized orbital on each carbon remains. The unhybridized pz orbitals on each carbon overlap to a
bond (pi).
