Physical Properties of Haloalkanes and Haloarenes

What happens when iodo and bromo alkanes are exposed to light?

Why do haloalkanes not show any colour in its pure state?

The solubility of haloalkanes is greater in water.

Order of density of haloalkanes for same alkyl group is $\mathrm{R}-\mathrm{I}>\mathrm{R}-\mathrm{Br}>\mathrm{R}-\mathrm{Cl}>\mathrm{R}-\mathrm{F}$.

Compare the density of haloalkanes to water.

Discuss the density of haloalkanes.

Haloalkanes are completely soluble in water.

Which is the correct increasing order of boiling points of the following compounds?
$1-$Bromoethane, $1-$Bromopropane, $1-$Bromobutane, Bromobenzene.

The density of haloalkanes increases with the increase in the number of a carbon atom and atomic mass of halogens.

Which of the following alkyl halides produce colour when exposed to light?

A student has performed an experiment in the laboratory. He mixed water with hexane and found two layers separated. Second time he mixed chloroform with water, and he again found two layers in the test tube. Explain which will be upper layer and which one will be lower layer in both the experiments.

Arrange the following compounds in order of increasing boiling points.

$1$-Bromopropane, isopropyl bromide, $1$-bromobutane.
