Question

Which of the following is the most stable conformation of the compound?

A) Chair conformation
B) Boat conformation
C) Twist-boat conformation
D) Zigzag conformation

Answer 1

The most stable conformation of the compound is the chair conformation, which minimizes repulsive interactions between hydrogen atoms.

Step-by-step explanation:

The most stable conformation of the compound is the chair conformation.

The chair conformation of cyclohexane is preferred because it results in fewer repulsive interactions between the hydrogen atoms. In this conformation, all bonds in the cyclohexane ring are close to the tetrahedral angle of 109.5 degrees, reducing ring strain.

Although other conformations like the boat conformation, twist boat conformation, and zigzag conformation exist, the chair conformation is the most stable and predominant in cyclohexane.
