is still considered as a partially fluorinated aliphatic compound. It has one non-hydrogen bonded -CF3group, one >CH- group, one chlorine atom, and one bromine atom. There is also a correction for partial fluorination. TB = 198.0 + l(-CF3) + l(>CH-) + l(-Br) + l(-Cl) + partially fluorinated = 198.0

+ 29.96 + 21.74 + 66.86 + 38.13 + (-25.0) = 329.69 K

(5) Trifluorochloromethane (CF3Cl). It is a perhalogenated aliphatic compound containing one non-hydrogen bonded -CF3 and one C1 atom. There is also a correction for perhalogenation. TB = 198.0 + l(-CF3) + l(-Cl) + perhalogenated = 198.0

+ 29.96 + 38.13 + (-53.55) = 212.54 K

(6) l,l,l-Trichloroethane (CH3CC13). It is a partially halogenated aliphatic compound containing one -CH3 group, one >C< group, and three C1 atoms but no F. There is also a correction for partial halogenation. TB = 198.0 + l(-CH3) + 1(>C
