Halogen functional group, 787 table

Table 8 1 illustrates an application of each of these to a functional group transfer matron The anionic portion of the salt substitutes for the halogen of an alkyl halide The metal cation portion becomes a lithium sodium or potassium halide... 

Table V is also an index to Table I it classifies the compounds according to the functional groups they contain. One frequently wants to examine data on carbonyl compounds, on unsaturated or halogenated ketones, or another more or less specific class of substances, and the purpose of Table V is to simplify searches of this sort. Pyruvic acid appears in Table V both among the ketones and among the carboxylic acids, and Inspection of either group would quickly reveal any closely related compound that appears in this volume.

We have computed the surface areas, IT, halogenated derivatives, some of which also bear other functional groups. These data are listed in Table 4, along with experimentally determined boiling points and critical temperatures. 

In order to determine the degree and rate of consumption of NBS by other functional groups in a peptide chain, a number of amino acids and their derivatives were treated with NBS, the disappearance of positive halogen being followed by thiosulfate titration. As summarized in Table... 

Table 1.3 shows the approximate values for common functional groups. The lower the value, the more acidic the protonated species. Any conjugate acid in the table will protonate a species lying below it and will be protonated by acids listed above it. Thus, a halogen acid (pK of -10 to -8) will protonate any species listed in this table, whereas a carboxylic acid (pA a of 4-5) would be expected to protonate aliphatic amines ipK values of 9-11), but not primary and secondary aromatic amines ipK values of -5 and 1, respectively).
