Which of the following statements is/are correct? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: London dispersion forces depend on molecular size, surface area, and polarizability, whereas dipole-dipole forces depend on dipole moment, and hydrogen bonds are exceptionally strong. Step 2: Comparing the options, we find that (a), (b), and (c) all correctly reflect the trend of intermolecular forces based on molecular weight, surface area, polarity, and hydrogen bonding. Step 3: The order in (d) is incorrect because OBr2 experiences only dispersion forces and no hydrogen bonding, so its molecular forces do not follow this sequence.
