Does benzene absorb UV light?
Does benzene absorb UV light? Note that both benzene and naphthacene absorb light in the near ultraviolet but that the latter does so much more intensely. A solution of naphthacene will absorb almost 100 times as much light at 250 nm. as a solution of benzene of the same molar concentration. Can light break bonds? […]
