Vedclass · Answer

(D) An auxochrome is a group of atoms which,when attached to a chromophore,modifies the ability of the chromophore to absorb light,often shifting the absorption to longer wavelengths. Groups like $-N(CH_3)_2$,$-OH$,and $-OCH_3$ contain lone pairs of electrons that can interact with the $\pi$-system of a chromophore,thus acting as auxochromes. $(D)$ $>C=N$ is a chromophore itself,not an auxochrome.

Which of the following groups is not an auxochrome?
