This is a ranking of the given compounds in order of increasing boiling points:

CH3-CH2-OH < CH2=CH2 < CH3-CH3 < CH3CE < CH4

This is based on the molecular weights and intermolecular forces present in each compound. Methanol (CH3OH) has the lowest boiling point due to its small molecular weight and the presence of hydrogen bonding. Ethene (CH2=CH2) has a lower boiling point than ethane (CH3-CH3) due to its lower molecular weight. Acetone (CH3COCH3) has a higher boiling point than ethane due to the presence of polar C=O bonds. Finally, methane (CH4) has the highest boiling point due to its nonpolar nature and small molecular weight.
