quantum theory of covalent bond

Single, double and triple covalent bonds differ from each other in the following ways. Single bond is formed by the sharing of one electron pair, (two electrons); a double bond is formed by the sharing of two electron pairs, (four electrons), whereas a triple..

Single bond is formed by the sharing of one electron pair, (two electrons); a double bond is formed by the sharing of two electron pairs, (four electrons), whereas a triple bond involves sharing of three electron pairs, (six electrons..

Two new theories came to substantially modify Bohr's Atomic model. They a..

In covalent crystals, the constituent particles are atoms of the same or different kind, which are bonded to one another by a network of covalent bonds. The important characteristics of covalent crystals are: The covalent crystals are i..

A covalent bond can be formed in different ways. When a bond is formed by mutual sharing of one pair of electrons it is known as a 'single covalent bond', or simply 'a single bond..

The covalent compounds do not exist as ions but they exist as molecules They exist at room temperature, as liquids or gases. However, a few compounds also exist in the solid state e.g. urea, sugar, etc. The melting and boiling points of covalent compounds are generally low ..

Molecular hydrides are formed by the combination of elements of comparatively higher electronegativity as of p block elements. These bonds are mostly covalent in character with partly ionic character too (for example, in HF). These hydrides, therefore have molecular lattices he..

1) Covalent compounds consist of molecules and not ions. The molecules do not have any electric charge on them. The molecules are held together by weak forces called Van der Waal's forces . 2) Covalent compounds are either gases, volatile liquids or soft solids. As there are wea..

The steps in writing Lewis structures of covalent compounds are as follows: of the molecule by placing the atoms of the combining elements properly. Usually an atom, which forms the largest number of bonds with other atoms is written as the central atom of the structure. For exa..

Molecular hydrides are soft. They are generally, volatile in nature and have low melting and boiling points. They have low electrical conductivity. The electronegativity difference between hydrogen and the atom bonded to it, determines the properties of covalent hydri..
