(a) Impure compounds tend to have lower melting points than pure samples. Explain why this occurs, using biphenyl as an example. Make sure you consider what happens upon melting in molecular terms. (b) Is recrystallization a suitable method for purifying all types of organic compounds? If not, why not?
