(a)

Interpretation Introduction

Interpretation:

The energy barrier of given compounds should be predicted.

Concept Introduction:

Newman projection:

  • The conformational isomers are representing by the Newman projection drawing.
  • Newman projection representing by front carbon atom connected to 3 groups then the 3 groups connected circle is a back carbon atom.
  • In the Newman projection, the atoms or groups are attached to the center carbon by angle of 60° and this is called as a dihedral angle.
  • The dihedral angle is varying by the rotation of C-C bond, result of this there are two conformations are obtained and this are staggered and eclipsed conformations obtained.
  • The highest energy conformation is eclipsed and lowest energy conformation is staggered.

To predict: the energy barrier for the given compounds.
