Select the correct statement about amines from the follwoing.

Arrange the following in increasing order of boiling points :
${\left({\mathrm{CH}}_3\right)}_2\mathrm{NH}, {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}, {\mathrm{C}}_2{\mathrm{H}}_5{\mathrm{NH}}_2$

Account for the following :

Ethylamine is soluble in water whereas aniline is not.

Given below are two statements :

Statement I : Pure Aniline and other arylamines are usually colourless.

Statement II : Arylamines get coloured on storage due to atmospheric reduction.

In the light of the above statements, choose the most appropriate answer from the options given below :

Give reasons : ${\left({\mathrm{CH}}_3\right)}_2\mathrm{NH}$ is more basic than ${\left({\mathrm{CH}}_3\right)}_3\mathrm{N}$ in an aqueous solution.

Arrange the following compounds in decreasing order of their boiling points:

Butanol, Butanamine, Butane

Explain the following :

Amines are less acidic than alcohols of comparable molecular masses.
