It increases the color of any organic compound. For example, benzene does not display color as it does not have a chromophore; but nitrobenzene is pale yellow color because of the presence of a nitro group (−NO2) which acts as a chromophore. But p-hydroxynitrobenzene exhibits a deep yellow color, in which the −OH group acts as an auxochrome. Here the auxochrome (−OH) is conjugated with the chromophore −NO2. Similar behavior is seen in azobenzene which has a re… WebApr 28, 2015 · A second, that heteroatoms next to a $\ce{C=O}$ carbonyl group induce a hypsochromic shift like in the case of acetaldehyde example here in comparison to …
