Bonding and Solubility Hydrogen bonding raises the boiling point of alcohols. • Ethanol: 78C >Chloroethane( CH3CH2Cl): 12.3C> ethane: -88.6C The longer the carbon chain in an alcohol is, the lower the solubility in polar solvents and the higher the solubility in nonpolar solvents. Methanol Ethanol Propanol
