Why is the free single bond rotation restricted in the case of cyclic compounds?
1 Answer
Because
Explanation:
Get a set of molecular models and make models of ethane and cyclohexane. The methyl residues of ethane can rotate with respect to each other around the
Now compare the cyclohexane structure. A degree of conformational change is possible for cyclohexane: boat; twist-boat; chair. But this conformational change is tightly constrained by the ring, and
