_ hybridization leads to a regular tetrahedral structure:
Correct answer: A. sp3
- A. sp3
- B. sp2
- C. sp
- D. All of these
Explanation
In hybridization, carbon's 2s and three 2p orbitals combine into four identical orbitals, now called sp3 hybrids. In the water molecule, the oxygen atom can form four sp3 orbitals.Two of these are occupied by the two lone pairs on the oxygen atom, while the other two are used for bonding.

About Hybridization
Hybridization explains bonding by combining atomic orbitals to form equivalent hybrid orbitals with definite geometries. Coverage includes sp, sp², sp³, sp³d and sp³d² hybridization, their shapes and bond angles, and the relation of sigma and pi bonds to molecular structure.
