Bromine forms a number of oxides of varying stability.
(a) One oxide has 90.90% Br and 9.10% O. Assuming its empirical and molecular formulas are the same, draw a Lewis structure of the molecule and specify the hybridization of the central atom (O).
(b) Another oxide is unstable BrO. Assuming the molecular orbital diagram in Figure 9.16 applies to BrO, write its electron configuration (where Br uses 4s and 4p orbitals). What is the highest occupied molecular orbital (HOMO) for the molecule?

Data given in Figure 9.16
