Organic compounds magnetic susceptibility

NOTE Extensive listing of magnetic susceptibilities of elements and organic and inorganic compounds can be found in G, Foex, Tables de constantes et donnes numeiiques, Massou et Cie, Paris, 1957,... 

According to P. Pascal,0 fluorine is diamagnetic the specific magnetic susceptibility is —3447 X10 j and the atomic susceptibilitv calculated from the additive law of mixtures for organic compounds is —63X10-1. Ionic fluorine is univalent and negative. The decomposition voltage required to separate this element from its compounds is 1 75 volts.7 The ionic velocity (transport number) 8 of fluorine ions at 18° is 46 6, and 52-5 at 25° with a temp, coeff. of 0 0238. 

The diamagnetic properties of homologous series of organic compounds were first investigated by Henricksen (1888), who called attention to the additive character of the magnetic susceptibility per gram molecule. 

From magnetic susceptibility and conductance measurements, it can lie shown that all these halogen-containing compounds obtained by alkylation reactions are nonelectrolytes in nonpolar organic solvents and have the structure (LXV). 

The existence of the free radicals has been demonstrated by physical as well as chemical means, the most important of which is the measurement of their magnetic susceptibilities. Practically all nor mal organic compounds have an even number of electrons existing...
