Question

what is hybridization ​

Answer 1

HYBRIDISATION:

• The process of mixing of atomic orbitals belonging to the same atom of slightly different energies so that a redistribution of energy takes place between them resulting in the formation of new set of orbitals of equivalent energies and shape is called hybridisation . The new orbitals thus formed are known as hybrid orbitals. Unlike pure orbitals, the hybrid orbitals are used in the bond formation.
• It is a hypothetical concept and has been introduced by Pauling and Slater in order to explain the characteristic geometrical shapes of poly atomic molecules such as CH4; NH3;H2O.
• The energy required for excitation of electrons becomes available when the combining atoms approach each other because energy is released when combining atoms approach each other.

Note: That is why hybridisation never takes place in isolated atoms but occurs only at the time of bond formation.

• The shape of hybrid orbitals (e.g. made from s - and p - orbitals) is like that of p - orbital except that the two lobes are unequal in size,i.e. there is one small lobe ( with - ve sign) opposite to a big lobe ( with + ve sign) on the other side ( fig.2.24).

Answer 2

Answer:

The process of an animal or plant breeding with an individual of another species or variety is called hybridization..
