Halogens binary acids

Reaction of Alcohol and Hydrobromic Acid.—The third reaction which proves the presence of the hydroxyl group in alcohol is with the halogen binary acids. When hydrochloric, or better hydrobromic or hydriodic acid, acts upon hot alochol a partial decomposition of the alcohol takes place and the ethyl halide and water are formed... 

Recall that, because of the strong H-F bond, hydrofluoric acid is a weak acid with a small acid dissociation constant Ka of 6.8 x 10-4. In contrast, the other binary acids of the halogen family—HC1, HBr, and HI—are strong acids that completely dissociate in water.) The fluorosilicic acid produced, H2SiF6, is a water-soluble substance with a structure as in Fig. 6.3.1. 

In the case of the halogen acids which are binary acids or non-oxygen acids the esters are the same as the alkyl halides, i.e., halogen substitution products of the hydrocarbons. With the oxygen acids, e.g., nitric, sulphuric, etc., the esters are not simple substitution products of hydrocarbons. With these inorganic acids which contain oxygen the acid... 

Objective 12 Binary acids are named by writing hydro followed by the root of the name of the halogen, then -ic, and finally acid (Table 5.2) ... 

Binary acids are named by writing. name of the halogen, then. 

The halogens form a series of binary acids called the hydrohalic acids. The strengths of the hydrohalic acids increase in the following order ... 

The reactivity, toxicity, and oxidizing ability of the halogens decrease from fluorine to iodine. The halogens all form binary acids (HX) and a series of oxoacids. 

An acid is a distinct type of molecular compound. Most acids used in the laboratory can be classified as either binary acids or oxyacids. Binary acids are acids that consist of two elements, usually hydrogen and one of the halogens— fluorine, chlorine, bromine, iodine. Oxyacids are acids that contain hydrogen, oxygen, and a third element (usually a nonmetal). 

HCo(CO)4are strong acids in aqueous solution. Both types of anions form precipitates with heavy metal ions such as Ag+ in aqueous solution. The parallels between seven-electron halogen atoms and 17-electron binary carbonyl species are sufficiently strong to justify applying the label pseudohalogen to these carbonyls.29...
