(a) Interpretation: The reason corresponding to the fact that glycine does not actually exist in the form with all atoms uncharged, but actually exist as a salt called zwitterion is to be explained. Concept introduction: The dipolar ion that possesses two or more than two functional groups in which one group has positive charge and other group has negative charge is known as zwitter ion. In zwitter ion, the net charge is always equals to zero.

Solution Summary: The author explains that glycine does not exist in the form with all atoms uncharged, but actually exist as a salt called zwitterion.
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.

(a)
Interpretation: The reason corresponding to the fact that glycine does not actually exist in the form with all atoms uncharged, but actually exist as a salt called zwitterion is to be explained.

Interpretation Introduction
(b)
Interpretation: The product formed by the reaction of glycine with concentrated HCl is to be predicted.
Concept introduction: An atom or a group of atoms that shows characteristic physical and chemical properties are collectively known as functional groups. The functional group is the most reactive part present in the molecule. The main functional groups are OH (alcoholic group), COOH(carboxylicgroup), CHO(aldehydicgroup)) and C=O(ketonicgroup).
According to Bronsted-Lowry theory, the species that easily accept the proton is known as base and the species that easily donate the proton is known as acid. The reaction of an acid with a base always leads to the formation of conjugate acid and base.
Interpretation Introduction
(c)
Interpretation: The product formed by the reaction of glycine with NaOH is to be predicted.
Concept introduction: An atom or a group of atoms that shows characteristic physical and chemical properties are collectively known as functional groups. The functional group is the most reactive part present in the molecule. The main functional groups are OH (alcoholic group), COOH(carboxylicgroup), CHO(aldehydicgroup)) and C=O(ketonicgroup).
According to Bronsted-Lowry theory, the species that easily tends to accept the proton is known as base and the species that easily donate the proton is known as acid. The reaction of an acid with a base always leads to the formation of conjugate acid and base.
