Cherries Posted May 9, 2018 Report Share Posted May 9, 2018 (edited) Bromine was added to hexane, hex-1-ene and benzene. Identify the compound(s) which will react with bromine in a well-lit laboratory. Answer (according to markscheme): hexane AND hex-1-ene; Accept "benzene AND hexane AND hex-1-ene" I thought that the answer would be hex-1-ene and benzene as hexane is saturated (the bromine water test). Why is it not? Edited May 9, 2018 by Cherries Reply Link to post Share on other sites More sharing options...
kw0573 Posted May 9, 2018 Report Share Posted May 9, 2018 hexane reacts with bromine by free radical substitution. Benzene was put down as an optional answer because it needs an additional acid catalyst, which is out of SL syllabus. 1 Reply Link to post Share on other sites More sharing options...
