Shapes of molecular orbitals
WebbThe two 2py atomic orbitals on the carbon atoms can overlap to form π molecular orbitals. As with overlap of atomic orbitals to form σ molecular orbitals, when the two 2py atomic orbitals overlap two π molecular orbitals are formed. The Hückel approximation is used to determine the energies and shapes of these two π orbitals.

WebbThere are four different kinds of orbitals, denoted s, p, d and f each with a different shape. Of the four, s and p orbitals are considered because these orbitals are the most common … WebbMolecular orbitals are made from linear combinations of atomic orbitals. We obtain these orbitals by adding or subtracting the equations that describe the energies of atomic orbitals. Adding orbitals with the proper sign of the wave function corresponds to constructive overlap of atomic orbitals.
