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)..

These molecules are called constitutional (or structural) isomers because they share the same chemical formula but have different patterns of atomic connectivity. Draw as many constitutional isomers as you can for C5H8 in bond-line notation. It may be helpful to draw a Lewis Structure for one of the isomers first.
