Question

What is sp²-hybridisation?​

Answer 1

Answer:

In sp² hybridization, one s orbital and two p orbitals hybridize to form three sp² orbitals, each consisting of 33% s character and 67% p character. This type of hybridization is required whenever an atom is surrounded by three groups of electrons. Created by Jay.

The process of intermixing of orbitals of same atom with nearly same energy to form equal number of new orbitals of equal energy is called Hybridisation.

$\large \bigstar \green{\underline {\underline{ \: Rules \: of \: hybridisation : - }}}$

✺ Orbitals of same atom only participate in hybridisation.

✺ Energy of hybridising orbitals must be equal

✺ The number of orbitals undergoing hybridisation must be equal to the number of orbitals hybridised.

✺ Only orbitals undergo hybridisation

✺ Hybrid orbitals form only σ bonds

$\large \bigstar \purple{\underline {\underline{ \: Types \: of \: hybridisation: - }}}$

It is classified on the basis of number of orbitals involved.
