WebBromine water becomes decolorised when it is reacted with ethene. However, bromine water is not decolorised when reacted with benzene. This indicates that. ? benzene is a saturated hydrocarbon. ? benzene is an aromatic hydrocarbon. ? … WebIn other words, isomerization reactions take place at a slower rate than other propagation reactions, e.g., β scission reaction. The critical importance of this observation is that the thermal cracking reactions produce shorter straight-chain alkanes and olefins without any significant formation of branched-chain (or iso-alkanes).
