Square planar molecules with formula AB2C2 and octahedral molecules with formulas AB4C2 and AB3C3 feature diastereoisomers. Recall that trigonal bipyramidal geometry features two distinct positions: axial and equatorial. Draw all diastereoisomers for trigonal bipyramidal molecules with formula (a) AB4C and (b) AB3C2. You must indicate the stereochemistry using full and dashed wedges and label all positions as either axial (ax) and equatorial (eq)..
