Question

Oxygen is not an auxochromic group. Justify the statement.​

Answer 1

An auxochrome is a functional group of atoms with one or more line pairs of electrons when attached to a chromophore, alters both the wavelengths and intensity of absorption. Examples:- Hydroxyl group (-OH), Amino group (-NH2), Aldehyde group (-CH2) and the methyl marcaptan group

Answer 2

Answer:

Oxygen exists as a gas due to a smaller size. The intermolecular forces between oxygen are weak van der Waals forces. So, oxygen exists as a gas. Sulphur exists as a solid because the atoms are held by strong covalent bonds. Which binds the atoms closely and strongly. Hence Sulphur exists as a solid.
