Question

Arrange the following substances in order of increasing boiling point CH3OH, CH4, CH3CH2OH, HOCH2CH2OH Multiple Choice O CH3OH

Answer 1

Answer:

The answer is: CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH

Explanation:

Boiling point refers to the temperature at which the pressure exerted by the surrounding on the liquid is equal to the vapor pressure of the liquid. The boiling point increases as the molar mass of the substance increases.

Since the molar mass increases in the order:

CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH

Therefore, the order of increasing boiling point:

CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
