1. draw the two chair conformations of the free radical bromination product of cyclohexane. which one is more stable? and why?
Homework Answers
The radical Bromination of cyclohexane
gives two chair products one is axial Bromo cyclohexane and another
is equatorial Bromo cyclohexane.
The equotorial Bromocyclohexane is more stable than axial Bromo cyclohexane because in axial form there is two Butane Gauch interaction between bromine and Hydrogen hence energy is 1.2 KCal/mol, in equotorial form no such interaction available hence energy is 0 kcal/mol . Lower is the energy more is the stability hence equotorial form of cyclohexane is more stable than axial form.

The cyclohexane derivative shown exists primarily in the more
stable of the two available chair conformations. Give the position,
axial or equatorial, of each of the three groups shown in the more
stable chair conformation. If a group divides its time equally
between axial and equatorial positions, indicate this with
ax/eq.
