Chapter 11.10, Problem 16P

Interpretation Introduction

Interpretation:

The structural formulas for the products of $\text{1,2}$ and $\text{1,4}$ addition of hydrogen chloride to $\text{2,4-hexadiene}$ are to be drawn.

Concept introduction:

>

The carbocation formed in the addition of hydrogen halide toa conjugated diene is resonance stabilized and forms two products.

>

In case of $\text{1,2}$ addition, the hydrogen and halogen atoms are bonded to the adjacent carbons of double bond in a conjugated diene system.

>

In case of $\text{1,4}$ addition, the hydrogen and halogen atoms are bonded to terminal carbons of conjugated double bonds.
