Final answer:
NH3 (Ammonia) central N hybridization: sp³, H₂O (Water) central O hybridization: sp³, BCl3 (Boron trichloride) central B hybridization: sp².
Explanation:
Hybridization types:
- NH3 (Ammonia) - sp³
- H₂O (Water) - sp³
- BCl3 (Boron trichloride) - sp²
Explanation: In NH3 and H₂O, the central atoms (N and O) form four bonds, leading to sp³ hybridization. In BCl3, Boron forms three bonds, resulting in sp² hybridization.
