In salts of the type of tetramethylammonium chloride,(CHJdNCI, and trimethylsulfonium chloride,(CH3) 2SCl, the radicals (CH3) kN and (CH&S play the part of metals, and like the metals can be arranged in an electropotential series or series of relative electro-affinities.* Tetramethylammonium and trimethylsulfonium thus occupy positions near the head of this series, comparable with the positions occupied by the alkali metals, which they resemble ...
