Why is it important to understand the isometric difference between two molecules

To differentiate between the structural properties of the chemical molecules.

Isomers of a chemical compound are two chemical compounds having the same chemical formula but different structure in three dimension.

Many physical and chemical properties are dependent on the structure of the chemical molecules.

These structural differences leads to many different bonding abilities to other molecules and leads to different properties like melting and boiling points.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.
