What structural characteristics give dyes their color? List two examples that fit this trend.
dyes are coloured, ionising, aromatic organic compounds, Dyes are aromatic organic compounds, and as such are based fundamentally on the structure of benzene or aryl compound.
Colour in dyes is invariably explained as a consequence of the presence of a Chromophore. Since, by definition, dyes are aromatic compounds their structure includes aryl rings which have delocalised electron systems
Example of structures which gives dye, its color
Ortho- and para- quinoid ring
chromophores
Nitro group (it also works as
structure to give dye its characteristic color)
ANswer
