Which pair of molecules are polar species? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Analyze the polarities of the molecules. CO2, BF3, CS2, and SO3 are highly symmetrical and non-polar (mu = 0). Step 2: SO2 is a bent molecule (sp2 hybridized with one lone pair) and is polar. SCl2 is also a bent molecule (sp3 hybridized with two lone pairs) and is polar. Step 3: Since both SO2 and SCl2 have non-zero dipole moments, they are both polar species, matching option (c).
