In O2 each oxygen atom is hybridized_________________?
Correct answer: B. sp2
- A. sp3
- B. sp2
- C. sp
- D. All
Explanation
In O2, each oxygen is commonly described as sp2 hybridized: two sp2 orbitals form sigma bonds or hold lone pairs, while an unhybridized p orbital participates in pi bonding. This arrangement supports the double-bond description of O2. Students may choose a by counting the two lone pairs and assuming four electron domains require sp3 hybridization.

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.
