explain the difference in melting point in terms of intermolecular forces involved:
1) Hexane(C6H14) m.p. = -96*C) vs octadecane(C18H38) m.p. = 28 - 30*C)
2) toluene((Ph-CH3) m.p. = 5.5*C) vs benzoic acid((Ph-CO2H) m.p. = 122.4*C)
3) benzoic acid((Ph-CO2H) m.p. = 122.4*C ) vs sodium benzoate((Ph-CO2Na) m.p. = 300*C)

1. Longer chain means more tangling of the chain is possible.
Look up IM forces in the text or on the web and try the other two yourself.
