Concept explainers
(a)
Interpretation: The barrier to rotation for the highlighted bond of the given molecule is to be calculated.
Concept introduction: Conformational isomers are defined as the type of stereoisomers in which the rotation about single bonds forms different spatial arrangements of atoms. It is of two types, eclipsed conformation and staggered conformation.
Steric strain is defined as an increase in potential energy that results when atoms are forced too close to one another.
Due to the repulsion between electrons in bond, the potential energy of the molecule increases. This increase in potential energy is referred as torsional strain.
