Question
Chapter 4, Problem 4.38P
Interpretation Introduction
Interpretation:
An explanation as to why the hydration reaction of ethylene is a very slow reaction is to be stated.
Concept introduction:
Hammond’s postulate states that the structure and energy of the transition state of a reaction depends on free energy of transition state. A reaction having intermediate with relatively higher free energy than the reactant and products can be approximated using the structure and energy of intermediate.

- Although benzene is normally written with three double bonds, benzene is not reactive towards many reagents that alkenes normally react with. This lack of reactivity can be explained by the unusual stability created by cyclic conjugation. First, (i) describe at least one of the physical properties of benzene that demonstrates how the true structure of benzene does match the way the structure is normally written. Then, (ii) explain how the unusual stability of benzene can be demonstrated by its thermodynamic properties through some form of experiment.
