i dont think there is any reaction between H2 and HBr.
they separate as they are alkenes and alkanes
Hydrogen and Bromine. Similar to hydrogen chloride it dissolves in water to form hydrobromic acid.
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.
bromine is reduced
bromine is reduced
no colour change
tribromophenol is formed.
the solution decolourised
nothing happens but you can add iodine then it will change coulur
2 bromophenol, 4 bromophenol and hydrogen bromide are formed
they separate as they are alkenes and alkanes
it changes colour form orangy-brown to colourless
Hydrogen bromide: HBr
Hydrogen and Bromine. Similar to hydrogen chloride it dissolves in water to form hydrobromic acid.
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.
Probable tetrabromoethane is formed.
bromine is reduced
