Step 1: Understand the concept of hybridization, which involves the mixing of atomic orbitals to form new hybrid orbitals suitable for the pairing of electrons to form chemical bonds.
Step 2: Analyze the molecular structure of O2. Oxygen in O2 forms a double bond, which involves one sigma (σ) bond and one pi (π) bond. The hybridization of oxygen in O2 is determined by the sigma bond.
Step 3: Determine the hybridization of oxygen in O2. Since the oxygen atom forms one sigma bond and has two lone pairs, it uses sp2 hybridization, which involves one s orbital and two p orbitals.
Step 4: Examine the molecular structure of H2O2. Each oxygen atom in H2O2 forms two sigma bonds (one with hydrogen and one with the other oxygen) and has two lone pairs.
Step 5: Determine the hybridization of oxygen in H2O2. The oxygen atoms in H2O2 use sp3 hybridization, which involves one s orbital and three p orbitals, to accommodate the two sigma bonds and two lone pairs.
