Question
Chapter 28, Problem 31P
Interpretation Introduction
Interpretation: The reason for Kinetic stability of Dewar benzene should be given.
Concept introduction:
Isomerization is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms are rearranged.
Each of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties is known as isomers.
If both atomic orbitals of the end groups turn in the same direction in an electrocyclic reaction then it is termed to be conrotatory.

The cyclohexane ring inverts approximately 10 time a second at room temperature.
