The determinations with toluol, chloroform, carbon tetrachloride 

 and tin tetrachloride-substances unlikely to form compounds with 

 chlorine^ — were made primarily with the object of fixing the freezing 

 point constant. The mean of these results gave K, 28-8, and from 

 this the latent heat of solid chlorine when calculated by the van't 

 Hoff equation is 20-4 calories per gram. 



The determinations with ethyl ether and ethyl acetate show nor- 

 mal results, i.e., these bodies exist in solution as single molecules. 

 Acetone is polymerized in concentrated solutions, while ethyl and 

 methyl alcohols are greatly associated in all dilutions. This is not 

 unexpected, since bodies containing the hydroxyl group are usually 

 polymerized, particularly at low temperatures. 



Two formulae are possible for the ether chlorine compound, 

 C4H10O <c! and C4HioO = Cl-Cl = Cl-Cl = OC4Hio 



(1) (2) 



Bromine, however, forms an analogous compound; so that its con- 

 stitution must be that of the chlorine complex. But in addition it 

 forms the compound C4HioOBr3, which can only be represented by 

 the straight chain type (2). We might then expect formula (2) for 

 the chlorine compound, and a constant of 14-5 for our cryoscopic 

 measurements instead of the normal value. Formula (1) from this 

 point of view is to be preferred.
