A trap to catch the resulting bromine-hydrogen bromide vapors is desirable. 

Bromine has also been suggested for an indirect detection process for the determination of tetracyclines in pharmaceutical formulations [155]. A bromine/hydrogen peroxide-based electrogenerated chemiluminescence reaction is shown to be enhanced by tetracycline derivatives and detection levels down to the pg dm level are reported on the basis of this enhancement effect. 

If someone in your class has been poisoned by chlorine, bromine, hydrogen sulphide, or carbon monoxide, take him or her out into the open air and immediately call a physician. 

Bromofluoromenthane has been prepared in high yield using a one-step reaction with bromine, hydrogen fluoride and methane in the presence of an aluminum trifluoride fluidized bed or fluorinated aluminum catalysts optionally containing cobalt or nickel between 450 and 500°C.20... 

The addition compound of trimethylamine and monobromo-borane has been prepared by reaction of trimethylamine-borane with either bromine or boron tribromide,4 but an excess of either reagent gives further bromination. Hydrogen bromide, however, gives only the monobromo derivative, even when added in excess. The synthesis is similar to that of trimethylamine-...

At temperatures above 500 °C more than 90 % of the organic bonded bromine was converted into bromide. By adding oxygen complete breakdown to carbon dioxide, bromide and water is possible. Under supercritical water oxidation conditions more than 99 % of the organic bonded bromine was found in the aqueous phase. A formation of bromine, hydrogen bromide and dioxines as in thermal decomposition was not observed. 

PROBLEM Identify the following elements as metals, nonmetals, or semimetals potassium, calcium, bromine, hydrogen, and neon. 

A model of the deuterated bromo compound shows that the deuterium, bromine, and the two carbon atoms that will constitute the double bond all lie in a plane. This arrangement of atoms leads to syn elimination. Even though anti elimination is usually preferred, it doesn t occur for this compound because the bromine, hydrogen, and two carbons can t achieve the necessary geometry. 

Regardless of the stereochemistry of the bromine, hydrogen is transferred from the less hindered side of the substrate. 

Bromine hydrogen bromide sodium bromide potassium bromide silver bromide. Iodine hydrogen iodide hydriodic acid potassium triiodide. 

The preparation of the cts-aquoamminebis(ethylenedi-amine)cobalt(III) nitrate is effected by treating a well-cooled, saturated solution of as-aquoamminebis(ethylene-diamine) cobalt (III) bromide with concentrated nitric acid. However, the cis nitrate crystallizes very slowly and, if the solution is left too long, bromine, hydrogen bromide, and nitric acid are formed.

But can the above bodies likewise replace other bodies — Are they the equivalents of chlorine, bromine, hydrogen, c. All chemists, admit this equivalence, at least for chlorine and its analogues. Let us see if this opinion is conformable to experience. 

The reaction of pentaarylbismuth with 1 equiv. of bromine, hydrogen chloride, hydrogen tetrafluoroborate, triphenylsilanol and triphenylborane results in the cleavage of one of the Bi-C bonds to form tetraarylbismuth(V) compounds (Section 3.3.1). 

The most frequently used method for the preparation of 1,2,4,5-tetrazines 2 is the oxidation of dihvdro-1,2,4,5-tetrazines 1 with nitrous acid, iron(III) chloride, nitric acid, or other oxidizing agents, such as chlorine or bromine, hydrogen peroxide, isopentyl nitrite or lead(IV) acetate. 

In Compound 2.5 there are two hydrogens attached to the carbon P to the bromine ( -hydrogen atoms), and two alkenes, E (trans) and Z (cis), can be formed from different antiperiplanar conformations... 

This salt appears to be stable indefinitely in air. It is unattacked by bromine, hydrogen bromide or hydrogen iodide, [34], but is nitrated by dinitrogen tetroxide or by nitric acid in acetic anhydride [35]. Other examples of substituted cyclopentadienide anions which can be handled in air include aroyl-, [20-22], fomyl-, [36], methoxycarbonyl-, [24,37-40], cyano-, [41-44], and methyl-sulphonyl-cyclopentadienides [45].
