Text Solution

AI Generated Solution

To explain why BH₄⁻ and NH₄⁺ are isolobal, we will analyze their electronic configurations, hybridization, and molecular geometry step by step. ### Step 1: Determine the Electron Count for BH₄⁻ - Boron (B) has 3 valence electrons. - Each hydrogen (H) contributes 1 electron, and there are 4 hydrogens, contributing a total of 4 electrons. - The negative charge (⁻) indicates an additional electron. **Calculation:** ...
