Bromine chloride BrCl

The addition of bromine chloride (BrCl) and amine-bromine chloride complexes to cyclopentadiene, isoprene and cis- and fraws-l,3-pentadienes has been also investigated74,77. The amine-bromine chloride complexes react with these dienes to give mixtures of bromochlorides in ratios markedly different from those obtained with BrCl. In particular, in analogy with Br2, BrCl gives significantly more 1,4-addition and the complexes give more anti 1,2-addition. Only Markovnikov 1,2-adducts have been reported for BrCl addition to these dienes. Furthermore, in the case of cyclopentadiene, 1,2-addition proceeds completely anti whereas 1,4-addition gives predominantly the cis adducts (equation 45). 

Bromine chloride (BrCl) is an irritating red, smelly liquid used to treat industrial and sewage wastes. 

The generation of HOBr can be effected by the hydrolysis of bromine gas (Br2) or liquid bromine chloride (BrCl), as in the reaction below. This type of HOBr generation requires the use of large gas cylinders and associated equipment, similar to using chlorine. It is only appropriate for large industrial process cooling systems. 

The halogens form a series of compounds with each other, which are called interhalogens. Examples are bromine chloride (BrCl), iodine bromide (IBr), bromine fluoride (BrF), and chlorine fluoride (CIF). Which compound is expected to have the lowest boiling point at any given pressure Explain. 

BrCl exists in equilibrium with bromine and chlorine in both gas and liquid phases. Table 5 lists various physical properties of BrCl. Due to the polarity of BrCl, it shows greater solubility than bromine in polar solvents. In water, it has a solubility of 8.5 gms per 100 gms of water at 20 C (that is, 2.5 times the solubility of bromine 11 times that of chlorine). Bromine chloride s solubility in water is increased greatly by adding chloride ions to form the complex chlorobromate ion, BrCl 2. 

The major organic reactions of BrCl consist of electrophilic brominations of aromatic compounds. Many aromatic compounds do not react in aqueous solution unless the reaction involves activated aromatic compounds (an example being phenol). Bromine chloride undergoes free-radical reactions more readily than bromine. 

Bromine chloride s reactivity with metals is not as great as that of bromine however, it is comparable to chlorine. Dry BrCl is typically two orders of magnitude less reactive with metals than dry bromine. Most BrCI is less corrosive than bromine. Like chlorine, BrCl is stored and shipped in steel containers. Also, Kynar and Viton plastics and Teflon are preferred over polyvinyl chloride (PVC) when BrCl is in the liquid or vapor states. 

At a certain temperature, K is 0.040 for the decomposition of two moles of bromine chloride gas (BrCl) to its elements. An equilibrium mixture at this temperature contains bromine and chlorine gases at equal partial pressures of0.0493 atm. What is the equilibrium partial pressure of bromine chloride ... 

Bromide and iodide in the presence of each other and of chloride The presence of a chloride does not interfere with the reactions described below. To the soda extract, strongly acidified with dilute hydrochloric acid add 1-2 drops of chlorine water (the solution obtained by carefully acidifying a dilute solution of sodium hypochlorite with dilute hydrochloric acid may also be used) and 2-3 ml chloroform or carbon tetrachloride shake a violet colour indicates iodide. Continue the addition of chlorine water or of acidified sodium hypochlorite solution drop by drop to oxidize the iodine to iodate and shake after each addition. The violet colour will disappear, and a reddish-brown colouration of the chloroform or carbon tetrachloride, due to dissolved bromine (and/or bromine monochloride, BrCl), will be obtained if a bromide is present. If iodide alone is present, the solution will be colourless after the violet colour has disappeared.
