Chapter 8, Problem 64P

Interpretation Introduction

Interpretation:

The reasonable mechanisms for each of the given reactions are to be suggested.

Concept introduction:

A molecule of hydrogen iodide adds to a double bond of an alkene to give the corresponding alkyl iodide. Hydrogen iodide is generally produced in situ with $\text{KI and H}\text{P}{\text{O}}_{\text{4}}$ because of its susceptibility to atmospheric oxidation and strongly reducing nature.

A molecule of ${\text{H}}_{\text{2}}\text{O}$ adds with a molecule of alkene, resulting in the production of an alcohol.

Bromine reacts with an alkene in aqueous conditions to convert it to halohydrin $\left(\text{β-halo alcohol}\right)$.
