H2SO4 is a weaker acid than HClO4. — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Hydrolysis of group 14 tetrahalides requires coordination of water molecules to the central atom via vacant d-orbitals. Step 2: Carbon (C) belongs to the second period and lacks vacant d-orbitals in its valence shell, preventing it from accepting lone pairs from water molecules to initiate hydrolysis. Step 3: Consequently, CCl4 does not undergo hydrolysis at room temperature, making option (c) the correct answer.
