15-21 Answer true or false. For a molecule with two stereocenters, 2 2 = 4 stereoisomers are possible. For a molecule with three stereocenters, 3 2 = 9 stereoisomers are possible. Enantiomers, like gloves, occur in pairs. 2-Pentanol and 3-pentanol are both chiral and show enantiomerism. 1-Methylcyclohexanol is achiral and does not show enantiomerism. Diastereomers are stereoisomers that are not mirror images.
