bonding of molecules

Hydrogen molecule The bonding between hydrogen atoms to form a molecule of hydrogen can be represented as follows: In this representation, half-filled '1s' orbital of one hydrogen atom overlaps (shown by 'dashed' lines) with that of the other having electron with ..

Bonding in Some Diatomic Molecules - Bonding in some homonuclear diatomic molecules of the elements of first and second rows of the periodic table: 1. Hydrogen molecule (H 2 ) 2. Hydrogen molecule ion (H 2 + ) 3. Hypothetical helium m..

Bonding in some homonuclear diatomic molecules of the elements of first and second rows of the periodic table: 1. Hydrogen molecule (H 2 ) 2. Hydrogen molecule ion (H 2 + ) 3. Hypothetical helium molecule (He 2..

In a molecule having three bond pairs of electrons around its central atom, the electron pairs form an equilateral triangular arrangement around the central atom. These molecules have trigonal planar (or triangularplanar) shape and the three bond pairs are a..

Molecule having four bond pairs of electrons around the central atom, arrange their electrons tetrahedrally. These molecules have tetrahedral shapes and the four bond pairs are at an angle of 10928' with respect to each other. Some molecules which ..

F ormation of oxygen (O 2 ) molecule Each oxygen atom has six electrons in its valence shell. Thus, it requires 2 more electrons to achieve the nearest noble gas configuration. This is achieved by sharing two pairs of electrons by the two oxygen atoms as shown below: ..

In a molecule having two bond pairs of electrons around its central atom, the bond pairs are located on the opposite sides (at an angle of 180 o ) so that the repulsion between them is minimum. Such molecules are therefore linear. Some molecules, w..

A molecule having three bond pairs, and one lone pair of electrons, has these four pairs of electrons distributed tetrahedrally around the central atom. A molecule of AB 3 type has a triangular pyramidal shape and is called a trigonal pyramidal molecule. Ty..

The pairs of electrons in the valence shell of an atom, which are not involved in bonding are called lone pair of electrons. Well known instances of these types of molecules are: the oxygen atom in water molecule H 2 O, has two lone pairs of electrons; the nitrogen at..

In polyatomic molecules the dipole moment not only depends upon the individual dipole moments of the bonds but also on the spatial arrangement of the various bonds in the molecule. In such molecules the dipole moment of the molecule is th..
