Here are the essential concepts you must grasp in order to answer the question correctly.
Stereochemistry
Stereochemistry is the study of the spatial arrangement of atoms in molecules and how this affects their physical and chemical properties. It is crucial for understanding isomers, particularly stereoisomers, which have the same molecular formula but differ in the orientation of their atoms in space. This concept is essential for predicting differences in boiling points, melting points, and reactivity between compounds.

Chirality
Chirality refers to the property of a molecule that is not superimposable on its mirror image, often due to the presence of one or more stereocenters. Chiral molecules exist as enantiomers, which can exhibit different physical properties, such as optical activity. Understanding chirality is vital for determining the absolute configuration of stereocenters and predicting how different enantiomers may behave in biological systems.

Physical Properties
Physical properties are characteristics of substances that can be observed or measured without changing the substance's chemical identity, such as boiling point, melting point, and solubility. These properties are influenced by molecular structure, including factors like intermolecular forces and molecular geometry. Analyzing physical properties helps in distinguishing between compounds, especially when considering isomers or stereoisomers.
