Chapter 6, Problem 6.2P

Interpretation Introduction

Interpretation: The conversion of A to B is to be classified as a substitution, elimination, or addition reaction.

Concept introduction: The substitution reactions involve the substitution or replacement of an atom or group of atoms in a compound by another atom or groups of atoms. In the substitution reactions, the replacement takes place by the break down of sigma bonds.

In elimination reaction, the formation of $\text{π}$ bonds occurs due to the removal of an atom or group of atoms from the starting material, whereas the addition reaction involves the addition of elements into the starting material.
