<p>4-Cyclopropylaniline is a terminal, mesogenic section with the cycloalkyl group. A liquid crystal is a phase of matter that displays an ordered arrangement of molecules and exhibits properties intermediate between those of liquids and solids. The molecules in a liquid crystal are typically rod- or disc-shaped, but can also be spherical. Liquid crystals have some degree of order at all times, but they may become more or less ordered over time. This can happen because the molecules are able to rotate freely within the liquid crystal's structure. Crystals are solid materials that have an orderly internal atomic structure. Crystals form when atoms or molecules attach to each other in a repeating pattern that extends in all three dimensions. Homologous compounds have similar molecular structures, which means they have similar chemical properties and react similarly with other compounds. The linkage between two adjacent carbon atoms is covalent bonding, while the linkage between two adjacent nitrogen atoms is called a single bond.</p>
