Bond angle
It is defined as the average angle between the orbitals of the central atom containing the bonding electron pairs in the molecule. It is expressed in degree/minute/second. This gives an idea about the distribution of orbitals around the central atom in a molecule. Therefore ..

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 - ...

Examples include ICl - 4 , XeF 4 and [Ni(CN) 4 ] 2 - ...Shapes of the molecules having only the bond (shared) pairs of electrons molecules with two bond pairs
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, which show linear geo..

In this case, one s- and two p-orbitals hybridize to form three sp 2 hybrid orbitals. These three sp 2 hybrid orbitals are oriented in a trigonal planar arrangement. For e.g., in BH 3 boron atom undergoes sp 2 hybridization and therefore, BH 3 has trigonal planar geometry and HBH bond ..
