Huckel theory of conjugated systems

Weba) The π molecular orbitals of buta-1,3-diene are derived from 2p atomic orbitals of carbon atoms, and there are four of them. b) Any orbital can accommodate up to two electrons, so buta-1,3-diene has eight π electrons. c) The complete set of molecular orbitals obtained by combining atomic orbitals includes an increased number of nodes.
