What is Bond Angle ? Explain.

Answer»

Solution :It is defined as the angle between the orbitals containing bonding ELECTRON pairs around the central ATOM in a molecule/complex ion.
Bond angle is expressed in degree which can be experimentally determined by spectroscopic methods.
Uses : It gives some idea regarding the DISTRIBUTION of orbitals around the central atom in a molecule/complex ion and HENCE it HELPS us in determining its shape.
For example H - O - H bond angle in water can be represented as under :
