Question

what is chromophore and auxochromes give example?​

Answer 1

Answer:

auxochrome and chromophore is that an auxochrome is a group of atoms that modify the structure of a chromophore, whereas a chromophore is a molecular moiety that gives the colour of the molecule. Chromophores are able to display a colour when it is exposed to visible light.

retinal (used in the eye to detect light), various food colorings, fabric dyes (azo compounds), pH indicators, lycopene, β-carotene, and anthocyanins. Various factors in a chromophore's structure go into determining at what wavelength region in a spectrum the chromophore will absorb.

Examples include the hydroxyl group (−OH), the amino group (−NH2), the aldehyde group (−CHO), and the methyl mercaptan group (−SCH3). An auxochrome is a functional group of atoms with one or more lone pairs of electrons when attached to a chromophore, alters both the wavelength and intensity of
