Solid structures containing discrete molecules

In ice and iodine the discrete units of the structure are molecules and when the solids fall apart the molecules retain their individual, discrete identity: ice melts to give water which also contains water molecules; iodine sublimes to give a vapour that still contains i

6 FAQs about [Solid structures containing discrete molecules]

What is solid state chemistry?

Solid state chemistry is the study of the synthesis, structure, properties and applications of solids. 1. They have fixed shape size and volume. 2. They are incompressible and inflexible. 3. The particles constituting a solid may be atoms (e.g, in metal), ions (e.g, in NaCl), or molecules (e.r, dry ice).

Which state of matter possesses the most structural diversity?

Chapter 2Solid-State ChemistryOf the three states of matter, solids posses the most structural diversity. Whereas gases and liquids consist of discrete molecules that are randomly distributed due to thermal motion, solids consist of molecules, atoms, or ions that are po

What are the properties of a molecular solid?

A molecular solid is composed of molecules held together by van der Waals forces. Its properties are dictated by the weak nature of these intermolecular forces. Molecular solids are soft, often volatile, have low melting temperatures, and are electrical insulators.

What are the different types of molecular solids?

Classes of molecular solids include organic compounds composed of carbon and hydrogen, fullerenes, halogens (F, Cl, etc.), chalcogens (O, S, etc.), and pnictogens (N, P, etc.). Larger molecules are less volatile and have higher melting points because their dispersion forces increase with the larger number of atoms.

What is a molecular solid?

Molecular solids are soft, often volatile, have low melting temperatures, and are electrical insulators. Classes of molecular solids include organic compounds composed of carbon and hydrogen, fullerenes, halogens (F, Cl, etc.), chalcogens (O, S, etc.), and pnictogens (N, P, etc.).

What are the properties of molecular crystals?

Discuss the properties of molecular crystals. A molecule is defined as a discrete aggregate of atoms bound together sufficiently tightly by directed covalent forces to allow it to retain its individuality when the substance is dissolved, melted, or vaporized. The two words italicized in the preceding sentence are important.
