Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

(a)

Interpretation Introduction

Interpretation:

The predominant form of carboxylic acid and an amine at pH 3.0 have to be drawn.

Concept Introduction:

If pKa is greater than the pH value then protonation occurs at that pH.

(b)

Interpretation Introduction

Interpretation:

The component that will be expected to be eluted first has to be identified and explained.

Concept Introduction:

In chromatography elution order depends on the solubility of the compound in stationary phase. Polar compounds are generally insoluble in non-polar stationary phase and hence eluted first. Whereas non-polar compounds are insoluble in polar stationary phase hence eluted first.
