Question

Propane (molar mass 44 11 g/mol) boils al -42 1 degreeC. Ethanol has almost the same molar mass (46.07 g/mol), but boils at 78 5 degreeC. which of the following BEST explains the reason for the large discrepancy in boiling point? When a compound name ends in 'or. the compound belongs to a family of compounds called alcohols Alcohols have an OH group Propane is ionic and. therefore, has a lower boiling point. Ethanol is ionic and. therefore, has a higher boiling point. Both compounds only exhibit van der Waals forces. Both compounds are polar Ethanol is more polar than Propane. Ethanol exhibits hydrogen bonding. Propane exhibits hydrogen bonding

Explanation / Answer

Ethanol exhibit intermolecular Hydrogen bonding. hence increase the attraction between the molecules, as a result it will be difficult to these attraction hence have to heat more to boil it
