Which one of the following conformations of cyclohexane is the least stable?

Options

  1. AHalf-chair
  2. BBoat
  3. CTwisted-boat
  4. DChair

Correct answer

A. Half-chair

Step-by-step solution

The stability order of conformation of cyclohexane is chair > twist boat > boat > half-chair Hence, half-chair is less stable due to torsional and angle strain.
