Tetrabromoethane

Tetrabromoethane (TBE) is a halogenated hydrocarbon, chemical formula C₂H₂Br₄. Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.
