Answer:

When one 's' orbital and 3 'p' orbitals belonging to the same shell of an atom mix together to form four new equivalent orbital, the type of hybridization is called a tetrahedral hybridization or sp3. ... Each sp3 hybrid orbital has 25% s character and 75% p character. Example of sp3 hybridization: ethane (C2H6), methane.

Answer:

Hybridization is defined as the concept of mixing two atomic orbitals with the same energy levels to give a degenerated new type of orbitals. This intermixing is based on quantum mechanics. The atomic orbitals of the same energy level can only take part in hybridization and both full filled and half-filled orbitals can also take part in this process, provided they have equal energy.

During the process of hybridization, the atomic orbitals of similar energy are mixed together such as the mixing of two ‘s’ orbitals or two ‘p’ orbital’s or mixing of an ‘s’ orbital with a ‘p’ orbital or ‘s’ orbital with a ‘d’ orbital.

What is Hybridization?

Redistribution of the energy of orbitals of individual atoms to give orbitals of equivalent energy happens when two atomic orbitals combine to form hybrid orbital in a molecule. This process is called hybridization. The new orbitals thus formed are known as hybrid orbitals

Examples of sp Hybridization:

All compounds of beryllium like BeF2, BeH2, BeCl2

All compounds of carbon-containing triple Bond like C2H2.

sp2 Hybridization

sp2 hybridization is observed when one s and two p orbitals of the same shell of an atom mix to form 3 equivalent orbital. The new orbitals formed are called sp2 hybrid orbitals.

hy2 bridization 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)

sp3 Hybridization

When one ‘s’ orbital and 3 ‘p’ orbitals belonging to the same shell of an atom mix together to form four new equivalent orbital, the type of hybridization is called a tetrahedral hybridization or sp3. The new orbitals formed are called sp3 hybrid orbitals.

These are directed towards the four corners of a regular tetrahedron and make an angle of 109°28’ with one another.

The angle between the sp3 hybrid orbitals is 109.280

Each sp3 hybrid orbital has 25% s character and 75% p character.

Example of sp3 hybridization: ethane (C2H6), methane.

sp3 Hybridization

sp3d Hybridization

sp3d hybridization involves the mixing of 3p orbitals and 1d orbital to form 5 sp3d hybridized orbitals of equal energy. They have trigonal bipyramidal geometry.

The mixture of s, p and d orbital forms trigonal bipyramidal symmetry.

Three hybrid orbitals lie in the horizontal plane inclined at an angle of 120° to each other known as the equatorial orbitals.

The remaining two orbitals lie in the vertical plane at 90 degrees plane of the equatorial orbitals known as axial orbitals.

Example: Hybridization in Phosphorus pentachloride (PCl5)

sp3d Hybridization
