Question

TYPES OF HYBRIDIZATION

Answer 1

Answer:

Q : What is Hybridization ?

Ans : Hybridization is the combining of different types of orbitals.

Q : Types of Hybridization ?

Ans : The following are the types of hybridisation:

1) sp – Hybridisation

In such hybridisation one s- and one p-orbital are mixed to form two sp – hybrid orbitals, having a linear structure with bond angle 180 degrees. For example in the formation of BeCl2

,first be atom comes in excited state 2s1 2p1, then hybridized to form two sp – hybrid orbitals. These hybrid orbitals overlap with the two p-orbitals of two chlorine atoms to form BeCl2.

2) sp2 – Hybridisation

In such hybridisation one s- and tow p-orbitals are mixed form three sp2– hybrid orbitals, having a planar triangular structure with bond angle 120 degrees.

3) sp3 – Hybridisation

In such hybridisation one s- and three p-orbitals are mixed to form four sp3– hybrid orbitals having a tetrahedral structure with bond angle 109 degrees 28′, that is, 109.5 degrees.
