Trang 4Bonding 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
Propanol in water 23C
