Select correct statement(s) regarding \sigma and \pi-bonds: — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Note that because ICl and Br2 have similar molecular sizes and masses, their London dispersion forces are comparable in strength. Step 2: However, ICl consists of two atoms with different electronegativities, making it a polar molecule with dipole-dipole intermolecular attractions. Br2 is homonuclear and completely non-polar, having only dispersion forces. Step 3: The additional dipole-dipole forces in ICl require more energy to overcome, resulting in a significantly higher boiling point. Thus, option (c) is correct.
