Analyzing each statement:

a) the ring strain is independent of the number of CH_{2} groups.

**False**. Number of CH_{2} groups are not related to ring strain

The cyclohexane ring is essentially free of ring strain because

Check all that apply.

a) the ring strain is independent of the number of CH_{2} groups.

b) the values of estimated and experimental heat of the combustion for cyclohexane are the same.

c) there is maximum torsional strain in the cyclohexane ring.
