Question

What structural characteristics give dyes their color? List two examples that fit this trend. ​

Answer 1

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)
