WebNov 20, 2024 · Chlorine, bromine and iodine react readily with alkenes. No catalyst or ultraviolet light is needed. (b) For example, when ethene is bubbled through a solution of bromine in water or tetrachloromethane in the dark, the red-brown bromine is decolourised and a colourless liquid, 1,2-dibromoethane, is formed. Webfirst step in drawing a Lewis structure is to calculate the total number of valence electrons in the molecule. Hydrogen is in Group 1 of the periodic table and therefore, has 1 valence electron. Bromine is in Group 17 of the periodic table and therefore has 7 valence electrons.
