Make sure to answer in very detail and high level: Q1. (a) Draw a set of resonance structures for the hypothetical molecule PH5, ensuring that P obeys the octet rule in each structure. Assume a structure analogous to that of PF5.
(b) To what point does PH5 belong?
(c) Using PH5 as a model compound, use a ligand group orbital approach to describe the bonding in PH5. Show clearly how you derive the symmetries of both the P atomic orbitals, and the LGOs of the H5 fragment. Don't forget to draw diagram to explain all answers
