Chapter 23, Problem 116SCQ

Interpretation Introduction

Interpretation:

The reason for why there is a high barrier to rotation arround a carbon–carbon double bond than carbon–carbon single bond has to be explained

Concept introduction:

In Orbital overlap model of bonding , two nuclei’s of two atoms are approach each other and overlap their atomic orbitals. As the overlapping the energy increases, the interaction decreases.

After some distance the minimum energy is reached and it corresponds to the bonding distance. The two atoms of nuclei begin to repel and energy increases.

There is a high barrier to rotation arround a carbon –carbon double bond than carbon-carbon single bond because higher energy require to break the pi-bond than the sigma bond.
