5. Molecular orbitals are formed by the overlap of atomic orbitals. Thus, n atomic orbitals can combine (overlap) to form n molecular orbitals. In 1,3-butadiene there are four atomic p orbitals which can combine to form four 7 molecular orbitals. In ethene there are two atomic p orbitals which can combine to form two y molecular orbitals. The drawings below show the different ways in which the p orbitals of ethene and 1,3- butadiene can be combined to form the...
