Chapter 23, Problem 23.78SP

Interpretation Introduction

Interpretation:

Draw a simplified orbital overlap picture of the $\pi$ bond broken by filling in the p-orbitals in the transition state.

Concept used:

The $\pi$ bond must be broken to convert a double bond in the cis configuration into a double bond in the trans configuration. This is achieved by rotating the double bond by ${90}^{\circ }$.
