bonding in organic molecules

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..

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 ..

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 opp..

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: ..

The four electron pairs (two bond pairs + two lone pairs) are distributed tetrahedrally around the central atom as shown below. The two lone pairs on the central atom repel the bond pair slightly inwards due to greater lone pair-bond pair repulsion. As a result, the h..

The four bond pairs are distributed in a planar distribution. The two lone pairs are in a direction at right angles to this plane. This gives a square planar shape to such molecules. Examples include ICl - 4 , XeF 4 and [Ni(CN) 4 ] 2 - ...
