WebBromine, in the form of bromine water (Br 2 (aq)) is an example of a halogen. Ethene will readily react with bromine, so the colour of the bromine water changes from red-brown to colourless. Bromine atoms will add across the double bond in ethene to produce just one product; 1,2-dibromoethane.

WebIn an addition reaction to an alkene two covalent C-Br bonds are formed, and the color of the bromine fades as the colorless product is generated. In a substitution reaction of a hydrocarbon a C-Br covalent bond is also formed, but this product is accompanied by release of of an equal molar quantity of hydrogen bromide gas. great clips medford oregon online check inWebAliphatic hydrocarbons are divided into three classes: alkanes have only single bonds, and are said to be saturated; alkenes and alkynes have carbon-carbon double or triple bonds, … great clips marshalls creekWebMany hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory.
