Is C18H36 a molecular solid?
C18H36, also known as octadecane, is a hydrocarbon and is classified as a molecular solid. It consists of long hydrocarbon chains that are held together by Van der Waals forces. In its solid state, octadecane forms a crystalline structure at lower temperatures, characteristic of molecular solids. Thus, it exhibits properties typical of molecular solids, such as relatively low melting points and softer textures compared to ionic or metallic solids.
