Chapter 15, Problem 15.26P

Interpretation Introduction

Interpretation:

The structures of two constitutional isomers are to be suggested for the reaction of $\text{1, 3-}$ butadiene with one equivalent of ${\text{Br}}_2$. The product that will be predominate on equilibrium is to be determined.

Concept introduction:

Conjugated dienes give two types of addition products-$1,2-$ addition and $1,4-$ addition products. The addition product $1,2$ indicates the addition of hydrogen halide at adjacent carbon and also, it is the major product. The addition product $1,4$ indicates the addition of hydrogen halides to carbons that have a $1,4$ relationship and also, it is the minor product.
