OBJECTIVES

•	To investigate and understand the reason for angle strain in fully saturated planar carbocyclic rings.

•	For cyclohexane, determine the angle strain in actual compounds by analysing experimental crystal structure data.

•	To compare the predicted angle strain (in planar rings) against that observed in actual compounds and account for the differences.

•	To closely examine the conformations of 3- to 6-membered carbocyclic rings and understand why these conformations are adopted in terms of the strain present in these systems.
