Chapter 15, Problem 15.51P

Interpretation Introduction

Interpretation:

The type of reaction that does not occur readily with benzene and why it does not occur has to be explained.

Concept Introduction:

The addition, elimination and substitution reactions are types of organic reactions which can be identified by the number of bonds to carbon in reactants and products.

Addition reaction:

When an unsaturated reactant becomes a saturated product, the reaction is said to be addition reaction.

Elimination reaction:

When a saturated reactant becomes an unsaturated product, the reaction is said to be elimination reaction.

Addition and elimination reactions are opposite to each other.

Substitution reaction:

When a group or an atom in the reactant is substituted by a group or an atom from the other reactant, the reaction is said to be substitution reaction.  In substitution reaction, the substitution occurs on the carbon from which a group or an atom is removed.
