A meso compound contains two or more chiral centers bonded in such a way that it is achiral. (Please find definition on page 141) T F 2. 4-methylcyclohexanol can exist as two stereoisomers. This question was NOT graded. (4-methylcyclohexanol exists in cis and trans configurations. Both of them, meso compounds. You can find the explanation on page 127) T F 3. OH H 3 C CH 3 HO and The molecules are a pair of enantiomers (As these molecules are not mirror images with each other, they are diastereomers. Please see page 125 for further explanation) T F 4.
