Among given species identify the isostructural pairs : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Isostructural species must have the same geometry/shape. Step 2: NF3 is pyramidal and BF3 is trigonal planar. BF4^- and NH4^+ both have 4 bond pairs and 0 lone pairs around the central atom, giving them both tetrahedral geometries. Step 3: Since both BF4^- and NH4^+ are tetrahedral, they are isostructural.
