Quatemary carbons in alkanes have been shown to affect their physical properites, particularly melting point, viscosity, and density. Tetraalkylmethanes such as 13-decyl-13- heptyltritriacontane are liquids, l while the corresponding n-CwHIo2 melts at 92 0C. 2 Levina and coworkers have noted that highly branched alkanes of a C9H20-C17H3S structure with two or three quaternary carbon atoms, separated by a methylene group, generally have ...
