(d) The π electrons in benzene can be modeled as particles in a ring. A reasonable length of the radius of the ring is the C-C distance (1.39 A) in benzene. Calculate the percentage of error in the longest wavelength of absorption HOMO-LUMO gap) in the benzene spectrum if the experimental absorption is 270 nm 6 marks] (e) An element has atomic number 33 and it is found in Group V and 4th period of the periodic table. Derive the ground state term symbol for the valence electrons found in the p orbital of the element. Explain your reasonings. 4 marks]
