he intermolecular forces

Intermolecular Forces - The attractive forces between molecules are called intermolecular forces. Intermolecular attractions hold two or more molecules together. Intermolecular attractions can be of the following types: 1) Dipole..

Intermolecular Forces and Interatomic Forces - When two wet glass plates are pressed together, they cannot be separated easily. This is because of the force of attraction existing between the atoms and molecules, and are electrical in origin. As the two isola..

Elastomers - Elastomers are polymers in which the polymer chains are held by weakest intermolecular forces. These forces permit the polymers to be stretched. A few cross links are introduced between the chains to help the polymer retract to its original position after ..

Liquids that have weak intermolecular forces are more volatile and have a higher vapor pressure. For e.g., vapor pressure of ethyl alcohol is greater than that of the wat..

The vapour pressure of a liquid depends upon the nature of the liquid. When intermolecular forces are weak, the molecules tend to escape readily and therefore, the equilibrium vapour pressure is high. Vapour pressure of liquids provides an indication of the magnitude of in..

The liquid state lies between the gaseous and the solid state. Liquids are neither completely disordered nor completely ordered. The cohesive forces between the liquid particles are strong enough to keep them together but these particles do not occupy fixed lattice sites and are relativel..

The covalent compounds do not exist as ions but exist as molecules. There are weak intermolecular forces between the molecules and hence they exist as liquids or gases at room temperature. However, a few compounds also exist in the solid state e.g. urea, sugar et..

In thermoplastics, the intermolecular forces are intermediate between elastomers and fibers and the polymer chain has no cross-links. Thus thermoplastics can be moulded on heating. These polymers have no cross-linking between chains. Examples: Polyethylene, polystyrene et..
