Question

For the molecule BH3:

a) Using the H 1s orbitals, what is the reducible representation that represents the B-H sigma bonds

b) Reduce the reducible representation to express it in terms of the irreps of the point group

c) Which of the B atomic orbitals are of appropriate symmetry to form bonding and anti bonding symmetry

d) Do any of the B atomic orbitals or symmetry adapted linear combinations (SALCs) of these H 1s orbitals form non bonding orbitals?

e) Construct the MO diagram showing the B AOs and which SALCs mix
