Looking at its properties, it may be a solid under normal conditions, which is caused by the interaction and arrangement of atoms in its molecular structure. The atoms in the molecule are closely connected by chemical bonds to form a specific spatial configuration, giving it a solid state.
Melting point is an important physical parameter. Due to the influence of intermolecular forces, such as van der Waals force and hydrogen bonds, the melting point of this substance is in a specific range. This force makes the molecules arranged in an orderly manner, and requires a specific energy to break, which then determines the melting point. The accurate determination of the melting point can help to judge the purity of the substance. The presence of impurities will interfere with the intermolecular forces and cause the melting point to change, so the melting point is often the basis for judging the purity.
The boiling point cannot be ignored either. When the external pressure reaches a certain degree, the substance changes from the liquid state to the gaseous state, and this temperature is the boiling point.
