Question

distinguish betwen sp and sp2 hybridisation​

Answer 1

Answer:

sp hybridization has 1s and 1 p orbital of an atom to give a new sp hybrid orbital.

$sp^2]$ hybridization has 1 s and 2p orbitals of an atom to give a new $sp^2$ hybrid orbital

Answer 2

Sp:- This type of hybridization involves the mixing of one ‘s’ orbital and one ‘p’ orbital of equal energy to give a new hybrid orbital known as an sp hybridized orbital.

sp hybridization is also called diagonal hybridization.

Each sp hybridized orbital has an equal amount of s and p character, i.e., 50% s and p character.

sp Hybridization

Examples of sp Hybridization:

All compounds of beryllium like BeF2, BeH2, BeCl2

All compounds of carbon-containing triple Bond like C2H2.

Sp2:-

sp2 hybridization is also called trigonal hybridization.

It involves mixing of one ‘s’ orbital and two ‘p’ orbital’s of equal energy to give a new hybrid orbital known as sp2.

A mixture of s and p orbital formed in trigonal symmetry and is maintained at 1200.

All the three hybrid orbitals remain in one plane and make an angle of 120° with one another. Each of the hybrid orbitals formed has 33.33% s character and 66.66% ‘p’ character.

The molecules in which the central atom is linked to 3 atoms and is sp2 hybridized have a triangular planar shape.

sp2 Hybridization

Examples of sp2 Hybridization

All the compounds of Boron i.e. BF3, BH3

All the compounds of carbon containing a carbon-carbon double bond, Ethylene (C2H4)
