Basic Character.—The alkyl amines then are analogous to alkyl halides, and we find a corresponding homologous series, e.g.j methyl amine, ethyl amine, propyl amine, etc. They are strongly basic compounds, in fact, they are of especial interest because they are more strongly basic than the ammonia from which they are derived.

The boiling points of the compounds in any homologous series increase as their molecular weights increase because of the increase in van der Waals forces. So the boiling points of the compounds in a homologous series of ethers, alkyl halides, alcohols, and amines increase with increasing molecular weight. (See Appendix I.)... 

Pecsar and Martin have measured the activity coefficients of homologous series of alkanes, chloromethanes, alkyl formates, aldehydes, amines, and alcohols in the solvents H water, 2-pentanone, and 2,3,4-trimethylpentane from 293 to 313 K. The solvents used were rather volatile and pre-saturators were essential. The work is not of high accuracy the quoted average error was 5 per cent but it is probably higher. The range of systems measured, however, makes the work interesting. The results were adequately correlated by relationships proposed by Pierotti et who have measured activity coefficients of... 

Aryl alkyl ketones undergo a two-step homologation to give a-aryl-a-alkylnitriles (23), via an imine [an A-(l-arylalkylidene)cyanomethyl amine (22)]. A mechanism is proposed, and several are ruled out. For example, a series of para-substituted...
