Vedclass · Answer

(D) chromophore is a group of atoms in a molecule that is responsible for its color. Common examples of chromophores include $-N=N-$ (azo group),$-NO$ (nitroso group),and $-NO_2$ (nitro group). The $-NH_2$ (amino group) is an auxochrome,which is a group that modifies the ability of a chromophore to absorb light but does not produce color on its own. Therefore,$-NH_2$ is not a chromophore.
