Interpretation:
The following questions regarding 1,3,5-cycloheptatriene are to be answered:
a) How many p atomic orbitals are present in 1,3,5-cycloheptatriene. b) How many molecular orbitals describe this conjugated system. c) How many are bonding molecular orbitals. d) How many are anti-bonding molecular orbitals e) Which molecular orbitals are filled with electrons. f) If this molecule absorbs a photon of UV light, between which two molecular orbitals the electron will move.
Concept introduction:
When atomic orbitals overlap among themselves equal number of molecular orbitals, bonding and anti-bonding, are produced. Electrons occupy the molecular orbitals following Auf bau, Pauli’s exclusion principle and Hund’s rule. When the molecule absorbs a photon of UV light, the electron will move from the highest occupied molecular orbital (HOMO) to lowest unoccupied molecular orbital (LUMO).
