The critical temperatures (K) and pressures (atm) of a series of halogenated methanes are as follows:
Compound: CCl3F , CCl2F2, CClF3, CF4
Critical Temperature: 471, 385 ,302, 227
Critical Pressure: 43.5 ,40.6, 38.2 ,37.0
A.List the intermolecular forces that occur for each compound.
B.Predict the order of decreasing 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 CR C Handbook of Chemistry and Physics, and suggest a reason for any discrepancies.
