Chloromethane, physical properties

Some physical properties of the chloromethanes are given in Table 7-7 their enthalpies of formation from the elements are given in Table VI-6. All four are colorless, with characteristic odors and with low boiling points, increasing with the number of chlorine atoms in the molecule. The chloromethanes do not ionize in water. [Pg.227]
