# What intermolecular bonding occurs in "methylated spirits"?

$\text{Methylated spirits}$ is MOSTLY $\text{ethyl alcohol}$, and is a widely used industrial solvent. A volume of $\text{methyl alcohol}$ or $\text{phenol}$ is added so that if you drink it you will go blind; the methanol denatures the ethyl alcohol; and thus commercial supply escapes the taxes and duties commonly levied upon alcohol. Methylated spirit might be up to 5% methanol by volume.....
$\text{boiling point:}$ $C {H}_{4} , - 164$ ""^@C; ${H}_{3} C - C {H}_{3} , - 89$ ""^@C; $C {H}_{3} O H , 64.7$ ""^@C; ${H}_{3} C - C {H}_{2} O H , 78.5$ ""^@C. The effect of hydrogen bonding as an intermolecular force is well-illustrated.
