What is H-Bonding?

Hydrogen, which is bonded covalently with strongly electronegative element, can again form an extra weak physical bond with electronegative element; such weak bond is known as hydrogen bond, i.e. The electrostatic force that binds H-atoms of one molecule with electronegative atom of the other molecule of the same substance or of the different compound or within the same molecule is known as H-bonding.

Chemistry | Notes
Preparation of Haloalkanes - General Method
Class: 12

a) From Alkane
When alkane is treated with halogen in presence of sunlight or heat energy, alkyl halide is formed.

General Introduction to Haloalkanes | Organic Chemistry Class 12

Organic Chemistry
General Introduction to Haloalkanes
Class: 12

The compounds which are formed by the replacing one hydrogen atom from alkane by halogen atom are called haloalkanes. They are also called alkyl halides.

These are represented by general formula RX where R is the alkyl group and X is the halogen group.

Ionic Equilibrium - Postulates of Arrhenius Theory of Ionization

Class : 12

In 1887, Svante Arrhenius, put forward a theory to explain the properties of electrolytes in solution. This theory is known as Arrhenius theory of ionization or electrolytic dissociation after his name. The main points of the modern form of the theory are given below.

Some Thermodynamic Terms 

In order to study the laws of thermodynamics, it is essential to understand certain terms quite oftenly used in thermodynamics. These terms have definite meaning. Some of the most commonly used terms are given below.

Conductors and Non-conductors
Class : 12

The substances which allow the passage of electric current through them are called conductors. It may, however, be pointed out that all conductors do not conduct electricity to the same extent. Depending upon the ease with which they allow the passage of electricity, they are termed as good conductors or poor conductors. Although it is not possible to sharply distinguish between the good and poor conductors, but a rough division is possible on the basis of relative ease with which the conductor allows the passage of electricity. The substances which do not conduct electricity are called non-conductors or insulators.
