Which of the following compound has the smallest bond angle (X — A — X) in each series respectively? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the hybridization of the central atom in each species. Step 2: In H3O+, NH3, and PCl3, the central atoms (O, N, P) have 3 bond pairs and 1 lone pair, which correspond to sp3 hybridization. Step 3: In BF3, Boron has only 3 bond pairs and 0 lone pairs, giving it sp2 hybridization, which is different from the others.
