WebNov 15, 2013 · Consequently, the boiling points of the branched chain alkanes are less than the straight chain isomers. The above extract from my book, mentions clearly that branching makes the molecule more compact and thereby decreases the surface area. Even for isomeric alkyl halides, the boiling points decrease with branching. WebC₃H₈. C₃H₈ adopts the general formula CnH2n+2CnH2n+2 which corresponds to a saturated hydrocarbon like a straight-chain alkane that has the maximum number of hydrogen atoms (2n+2) for the given number of carbon atoms (n). Saturated hydrocarbons never contain ______. A) single bonds. B) single and double bonds.

WebBoiling points The boiling points displayed are for “straight-chain” isomers, of which there are several. At room temperature, the first four alkanes are gases, and solids do not exist until around C17H36, however, this is approximate since various isomers have different melting and boiling temperatures.
