WebThe present accepted theory of auxochromic action assumes that on the addition of an auxochrome to a chromogen 1 {i.e. a substance which cóntains a chromophore group and gives a deeper-coloured compound on the addition of an auxochrome), a strain is induced on the benzene ring, varying in degree according to the auxochrome employed.

A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light.

The chemical reaction of a molecule is dominated by two frontier orbitals, namely the HOMO and LUMO. highland k12 homepage
