Choose the correct answer from the options given below:
(A). chair
(B). boat
(C). twist boat
(D). half chair
Choose the correct answer from the options given below:
Show Hint
The chair conformation is the most stable because it minimizes both steric and torsional strain, while the half-chair has the highest strain due to poor bond angles and steric clashes.

- (A) > (D) > (C) > (B)
- (D) > (C) > (B) > (A)
Show Solution
The Correct Option is B
Solution and Explanation
Cyclohexane conformations exhibit the following stability order:
- Chair conformation (A): Most stable, minimizing steric and torsional strain.
- Twist-boat conformation (C): More stable than the boat conformation due to reduced steric strain.
- Boat conformation (B): Less stable due to flagpole interactions, resulting in steric strain.
- Half-chair conformation (D): Least stable, exhibiting maximum steric and torsional strain.
