The intermolecular forces of attraction (i.e., H-bonding and van der Waals' forces) exist among pola — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the geometry of ethyne (C2H2): each carbon is sp hybridized, yielding a symmetric linear structure (H-C≡C-H). Step 2: Analyze the structures of the options: H2O2 is open-book (non-planar), NO2 is bent (sp2 with an odd electron), SnCl2 is bent (sp2 with one lone pair). Step 3: Carbon dioxide (CO2) is sp hybridized and linear (O=C=O). Therefore, C2H2 is isostructural with CO2, matching option (d).
