Arrange these compounds by their expected boiling point. Highest boiling point Lowest boiling point CH3OH, CH3CI CH4.

The given compounds are arranged according to decreasing boiling point as .

Explanation:

The temperature at which vapor pressure of a substance becomes equal to the atmospheric pressure is called boiling point.

Stronger is the intermolecular forces present the atoms of a molecule more heat will be required by it to break the bond between its atoms. Hence, more will the boiling point of the molecule.

In (methanol), there is hydrogen bonding present which is a stronger force. So, it will have highest boiling point as compared to and .

In (chloroform), there is more electronegative atom attached (Cl) is attached to less electronegative atom (C and H). So, electrons are more pulled towards the chlorine atom. So, boiling point of   is more than methane .

Thus, we can conclude that given compounds are arranged according to decreasing boiling point as .
