(a) Draw and label the appropriate d-orbital splitting pattern of the octahedral complex [Cr(H2O)6]3+ (including the d electrons) and calculate the ligand field stabilisation energy in terms of the ligand field splitting parameter (Δoh) and the spin-pairing energy, P. [2 marks]
(b) Identify complex A and B (below) as high spin or low spin. Use ligand field arguments to justify your answer.
