Which of the following statement (s) about cyclohexane is/are wrong ?

A

(a) Stability of different conformations of cyclohexane is: Chair > Boat > Twist boat > Half chair.

B

(b) Only the chair from is free from angle strain.

C

(c) Half chair has five C atoms is one plane and one C atom out of the plane. Hence, it has both eclipsing and bond angle strain and is the least stable conformer of cyclohexane.

D

(d) Twisting the boat to the skew boat conformation moves the 'flagpole' H atoms away from each other and reduces the eclipsing strain. Hence, the twist boat is more stable than the boat conformation.
