What is the three types of intermolecular forces in order from strongest to weakest?

Answer 1

It has dispersion forces, dipole dipole forces ,and hydrogen bonding.

Answer 2

* Dispersion Forces

also known as London Forces (named after Fritz London who first described these forces theoretically 1930) or as Weak Intermolecular Forces or as van der Waal's Forces (namd after the person who contributed to our understanding of non-ideal gas behaviour). * Dipole-dipole interactions * Hydrogen bonds

Answer 3

Classifying Intermolecular ForcesIn general, intermolecular forces can be divided into several categories. The four prominent types are:

1. Strong ionic attraction

   Recall lattice energy and its relations to properties of solid. The more ionic, the higher the lattice energy. Examine the following list and see if you can explain the observed values by way of ionic attraction:

   LiF, 1036; LiI, 737; KF, 821; MgF2, 2957 kJ/mol.

2. Intermediate dipole-dipole forces

   Substances whose molecules have dipole moment have higher melting point or boiling point than those of similar molecular mass, but their molecules have no dipole moment.

3. Weak London dispersion forces or van der Waal's forceThese forces alway operate in any substance. The force arisen from induced dipole and the interaction is weaker than the dipole-dipole interaction. In general, the heavier the molecule, the stronger the van der Waal's force of interaction. For example, the boiling points of inert gases increase as their atomic masses increases due to stronger Landon dispersion interactions.
4. Hydrogen bond

   Certain substances such as H2O, HF, NH3 form hydrogen bonds, and the formation of which affects properties (mp, bp, solubility) of substance. Other compounds containing OH and NH2 groups also form hydrogen bonds. Molecules of many organic compounds such as alcohols, acids, amines, and aminoacids contain these groups, and thus hydrogen bonding plays a important role in biological science.

5. Covalent bonding

   Covalent is really intramolecular force rather than intermolecular force. It is mentioned here, because some solids are formed due to covalent bonding. For example, in diamond, silicon, quartz etc., the all atoms in the entire crystal are linked together by covalent bonding. These solids are hard, brittle, and have high melting points. Covalent bonding holds atoms tighter than ionic attraction.

6. Metallic bonding

   Forces between atom in metallic solids belong to another category. Valence electrons in metals are rampant. They are not restricted to certain atoms or bonds. Rather they run freely in the entire solid, providing good conductivity for heat and electric energy. These behaviour of electrons give special properties such as ductility and mechanical strength to metals. zarceus@Yahoo.com

Answer 4

dispersion forces < dipole-dipole interactions < hydrogen bonds

Answer 5

It depends on what type of liquid it is. In water it is hydrogen bonding (a dipole-dipole attraction). It can also be called polar bonding.

Answer 6

van der Waals forces, and, in some, dipole interaction (the strongest of which is hydrogen bonding).

Answer 7

hydrogen bond dispersion bond dipole bond
