Drops of nitric acid reacts with P2O10 to gives: — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: The trimer of sulfur trioxide is cyclic γ-SO3 (S3O9). Step 2: In this cyclic structure, each sulfur atom forms a six-membered ring with alternating oxygen atoms (S-O-S-O-S-O-). Each sulfur is bonded to two sharing (bridging) oxygen atoms in the ring and two terminal, double-bonded oxygen atoms. Step 3: This gives a total of four oxygen atoms bonded to each sulfur atom in the trimer, corresponding to option (a).
