1. Stereoisomerism is encountered in the homologous series.

2. Cycloalkanes are studied in this chapter: introduction to stereoisomerism, ring strain, chair conformations (strain free conformations of cyclohexane), substituted cyclohexanes.

3. In chemistry, Conformational isomerism is a form of stereoisomerism in which the isomers can be interconverted just by rotations about formally single bonds (refer to figure on single bond rotation).
