Glycine not being an optically active compound is to be explained. Concept introduction: Amino acids are defined as organic compounds which contain amine ( -NH 2 ) and carboxyl ( -COOH ) functional groups , along with a side chain (R group) attached to each amino acid. Glycine is an amino acid that consists of a single hydrogen atom in its side chain with a molecular formula of NH 2 CH 2 COOH . Optically active compounds are those consist of a chiral centre and rotate a plane of polarized light in clockwise and anti-clockwise direction. To determine: The explanation of glycine for not having an optically active compound.

Solution Summary: The author explains that glycine is not optically active due to the absence of a chiral carbon in its structure.
Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.

Interpretation Introduction
Interpretation: Glycine not being an optically active compound is to be explained.
Concept introduction: Amino acids are defined as organic compounds which contain amine(-NH2) and carboxyl
(-COOH)functional groups, along with a side chain (R group) attached to each amino acid. Glycine is an amino acid that consists of a single hydrogen atom in its side chain with a molecular formula of
NH2CH2COOH. Optically active compounds are those consist of a chiral centre and rotate a plane of polarized light in clockwise and anti-clockwise direction.
To determine: The explanation of glycine for not having an optically active compound.
