The hybridization of the central atom will change when : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Find the hybridization of the central atoms before and after each reaction. Step 2: For NH3 (sp3) -> NH4+ (sp3), NH3 (sp3) -> NH2- (sp3), and H2O (sp3) -> H3O+ (sp3), the hybridization remains sp3. Step 3: For boric acid, H3BO3 has sp2 hybridization. Combining with OH- forms the borate ion [B(OH)4]-, which is tetrahedral with sp3 hybridization, resulting in a change.
