The structural formulas of glycerol and trichloropropane are given above. Both compounds are
liquids at 25°C.
(a) For each compound, identify all types of intermolecular forces present in the liquid. Explain why
glycerol has the higher boiling point in terms of the relative strengths of the intermolecular forces.

(b) Glycerol (molar mass 92.09 g/mol) has been suggested for use as an alternative fuel. The
enthalpy of combustion, AHcomb , of glycerol is -1654 kJ/mol. What mass of glycerol would
need to be combusted to heat 500.0 g of water from 20.0°C to 100.0°C? (The specific heat
capacity of water is 4.184 J/(g °C). Assume that all the heat released by the combustion reaction
is absorbed by the water.)
