bromine is an element with the appearance of deep red colour. it is noxious liquid. and it is one of the members of halogen elements. this element has an appreciable vapour pressure at room temperature. chemical properties of bromine group 17 melting point −7.2°c, 19°f, 266 k period...
At room temperature, hydrogen bromide is a colourless gas, like all the hydrogen halides apart from hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the large and only mildly electronegative bromine atom; however, weak hydrogen bonding is present in solid crystalline hydrogen br...
Bromine is a dense, mobile, fuming, reddish-brown liquid at room temperature. It has a highly unpleasant odor resembling that of chlorine. Bromine is slightly soluble in water and highly soluble in many organic solvents, including carbon disulfide, carbon tetrachloride, acetic acid, and aliphatic ...
(except copper, stainless steel; nickel, and Monel). Fire may result from contact with combustibles or organic matter at room temperature, and contact of this substance with water produces an explosion. Even under mild conditions this substance attacks organic compounds vigorously, often causing ...
complex is often accompanied by a change in colour tone of the reagent solution. Successful aminocarbonylation of organochlorides have also been reported, accomplished by pre-heating [79], rapid microwave heating during the reaction [83] and elevated reaction temperature (170 °C) [81], ...
It is the third-lightest halogen and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and ...
