Answer 1

Question:-

The important conditions for hybridisation are

a) The orbitals present in the valence shell of the atom are hybridised

b) The orbitals undergoing hybridisation should have almost equal energy.

c) Promotion of electron is essential condition prior to hybridisation

d) Only electrons undergo hybridisation but not orbitals.

Answer:-

a) The orbitals present in the Valence shell of the atom are hybridised.

→ Only Valence orbitals are mixed to form new hybrid orbitals and this was explained by Pauling to explain VBT (Valence Bond Theory) and nature of covalent bonds.

b) The orbitals undergoing hybridisation should have almost equal energy.

→ Yes , the orbitals should have almost equal energy to redistribute it equally of same shape and same energy.

Additional Information:-

Hybridisation:-

• Mixing of different shapes and approximate equal energy atomic orbitals, and redistribution of energy to form new orbitals of same shape and energy.

• These new orbitals are called Hybrid orbitals. This phenomenon is called Hybridisation.

• This may take place in ground or excited state.

• It occurs among orbitals of same atom.
