know benzene is colourless...but i can't seem to get my head around it at the moment! As benzene has delocalised electrons, it should require less energy to excite the electrons. And Visible light is a lower frequency to UV? So according to the equation: E=hv Benzene should be coloured as it absorbs visible light? I know this is wrong and it is colourless, but i can't see how it works? Thanks for any help in advance!
