Solution

The correct option is D

Boat


This cyclohexane conformation is known as boat.

Like the chair conformation, the boat conformation is free of angle strain. However, the boat conformation is less stable than the chair conformation by 11 kcal/mole. Boat conformation is less stable because some of the carbon-hydrogen bonds in boat conformation are eclipsed.

The boat conformation is further destabilised by the close proximity of the flagpole hydrogens. These hydrogens are 1.8 Å apart but the Vander Waal's radii are 2.4 Å. The flagpole hydrogens are also known as trans-nuclear hydrogens.
