The sp3 hybridization has what percent s character and what percent p character respectively?

The sp³ orbital hybridization has 25% s-character and 75% p-character.

Explanation:

Hybridization refers to the process of mixing of a given number atomic orbitals to form equal number of new hybrid orbitals. The three types of hybrid orbitals are sp³, sp² and sp.

The four sp³ hybridized orbitals are formed by the mixing of one s orbital and three p orbitals.

Thus s-character in a sp³ hybridized orbital = (1:4) * 100 = 25%

and p-character in a sp³ hybridized orbital = (3:4) * 100 = 75%

Therefore, the sp³ orbital hybridization has 25% s-character and 75% p-character.
