THE HYBRIDISATION OF ORBITALS

HYBRIDISATION: it is a phenomenon, mixing up of two or more atomic orbitals of different energies and form an identical hybrid orbital. SP3 HYBRIDISATION: the shape of this molecule is tetrahydral shape. the bond angle is 109.28' this is formed by the combination of one S and 3P orbitals. four SP3 hybrid orbitals are formed. SP2 HYBRIDISATION: the shape of the molecule is planer triangular. the bond angle is 120°. this is formed by the combination of one S and 2P orbitals. three SP2 hybrid orbitals are formed. SP HYBRIDISATION: the shape of the molecule is linear. the bond angle is 180°. this is formed by the combination of S and P orbitals. two SP hybrid orbitals are formed.
