Spin pairing and overlapping theory cann...

Spin pairing and overlapping theory cannot explain the equal bond length as well as equal bond angles in `CH_(4)` molecule. To explain the above facts we are in need of hybridization theory. Hybridization is the mixing of atomic orbitals of comparable energy and the numbe of atomic orbitals involved is equal to the number of hybrid orbitals formed of equal energy.
According to hybridization theory, the `%s` character in `sp^(3)` hybrid orbitals is :

`25%`

`33.33%`

`20%`

`16.66%`

Verified by Experts

The correct Answer is:

sp orbital is closer to nucleus, so has lower energy.

Hybridization is the mixing of atomic orbitals of comparable energy and the numbe of atomic orbitals involved is equal to the number of hybrid orbitals formed of equal energy. Increasing order of the energy of hybrid orbitals is :

`sp^(3)ltsp^(2)ltsp`

`sp^(2)ltsp^(3)ltsp`

`spltsp^(3)ltsp^(2)`

`spltsp^(2)ltsp^(3)`

4, 2
