Question

⏩ write about hybridization​

Answer 1

Answer :-

Hybridization may be defined as the mixing of two or more than two atomic orbitals of an atom having comparable energy to give an equal number of identical orbitals having same energy and shape.

All hybrid orbitals are oriented symmetrically to have maximum distance from each other.

Depending on the combination of atomic orbitals the hybridization may be of various types as; sp3 (1s and 3p orbitals combine to form 4 sp3 hybrid orbital.) , sp2 , dsp2 , sp etc.

=> sp- hybridization arises when one s and one p orbital combine to form two sp-orbital with 180° bond angle and linear shape to the molecule. The percentage of s and p are 50 %. Ex: C2H2 (acetylene)

=> sp2 hybridization arises when one s and two p orbitals combine to form three sp2 hybrid orbitals with bond angle of 120° and triangular planner shape where the s-character is 33.33% . Ex: C2H4(Ethylene)

=> sp3 hybridization arises when 1s and 3p orbitals combine to form 4 sp3 hybrid orbital with bond angle 109°''28' and shape as tetrahedral where the s-character is 25% . Ex C2H6 (Ethane)

 

Answer 2

HOLA MATE..!!

ANSWER:-

Hybridisation is defined as the mixing of the atomic orbitals belonging to the same atom but having slightly different energies so that a redistribution of energy takes place between them resulting in the formation of new orbitals of equal energies and identical shape.

The new orbitals thus formed are known as hybrid orbitals.

Hybridisation is defined as the mixing of the atomic orbitals belonging to the same atom but having slightly different energies so that a redistribution of energy takes place between them resulting in the formation of new orbitals of equal energies and identical shape.

The new orbitals thus formed are known as hybrid orbitals.

Important points about hybridisation

1)Only those orbitals which have approximately equal energies and belong to the same atom or ion can undergo hybridisation.

2)Number of hybrid orbitals produced is equal to the number of atomic orbitals mixed.
