Question

The critical temperatures and pressures of a series of halogenated
methanes are as follows:

(a) List the intermolecular forces that occur for each
compound. (b) Predict the order of increasing intermolecular
attraction, from least to most, for this series of
compounds. (c) Predict the critical temperature and pressure
for CCl₄ based on the trends in this table. Look up
the experimentally determined critical temperatures and
pressures for CCl₄, using a source such as the CRC Handbook
of Chemistry and Physics, and suggest a reason for any
discrepancies.
