Question

What is the difference between a cyclohexane planar and chair conformation?

Answer 1

Cyclohexane Planar doesn't exist in nature, it is either Chair or Boat conformations.

Explanation:

Cyclohexane Planar doesn't exist in nature, it is either Chair or Boat conformations, this is mainly due to the angular stain in the planar structure.

The bond angle in a planar cyclohexane is `120^@` however, for `sp^3` hybridized carbons the bond angle is `109.5^@`
