    C.,Clg, and tetrachlormethane, CCl^. Under the same con- ditious hexane yields, together with the two latter compounds, hexchlormesol, C^Clg, and hexchlorbenzol, 0^]^} Bromine likewise yields substitution-products, but not so readily as chlorine,^ but by the action of excess of bromine under the iniluence of heat and pressure, substitution-products are formed similar to those which are obtained by the action of chloride of iodine. CONSTITUTION OF THE PARAFFINS. 91 The paraffins whose constitution is known may be classed under four groups. (1) The Normal Paraffiiis. In these the carbon atoms are connected together by simple linkage, no one atom being con- nected with more than two others. Of these the following have been examined : Boiling Boiling point. point. Methane CH, gas Heptane, 98°-4. Ethane gas Octane, 125° Propane gas Nonane, 148° Butane 1° Dodecane, ri XT ^12^26 202° Pentane 38° Hecdecane, ^16-^32 278°. Hexane 70° (2) Isojmrafflns. These contain an atom of carbon connected with three other carbon atoms, the other carbon atoms being joined by single linkage. The following members of this'series are known: Boiling point. rCH3 Trimethylmethane, CH^ OH, -17° iCH^ fCH3 Dimethylethylmethane, CB. \ CH, + 30° ( C.,H, ' Krafft and Mcvz, Ber. Dm/srJi. Chcm.
