Choose AnswerChoose the Best Answer

A

The bulky substituent will shift to the equatorial position, reducing steric strain.

B

The axial position will become favored due to increased torsional strain.

C

Ring flipping has no effect on the stability of the substituent.

D

The molecule will remain in its original conformation regardless of ring flipping.

Understanding the Answer

Let's break down why this is correct

When the chair flips, the big group moves from the tight axial spot to the open equatorial spot. Other options are incorrect because The misconception is that torsional strain makes the axial position better; The idea that flipping does nothing is wrong.

Definition

Cyclohexane molecules exhibit chair conformations where axial and equatorial positions determine stability. Chair flips involve interchanging axial and equatorial hydrogens without breaking bonds. The positioning of substituents like methyl groups affects energy levels and steric interactions, impacting molecular stability and reactivity.
