The discussion centers on the hybridization of sulfur in sulfur dioxide (SO2) and selenium in selenium dioxide (SeO2). It highlights that sulfur in SO2 is sp2 hybridized due to its discrete gaseous molecular structure, while selenium in SeO2 is sp3 hybridized, attributed to its solid polymeric structure with zig-zag chains. The conversation critiques the explanation in a textbook, questioning the validity of hybridization claims based on bond angles. It emphasizes that SO2 exists only in gaseous form, while SeO2's solid state shows bond angles between 90 and 100 degrees, suggesting that a more straightforward approach without hybridization assumptions might better describe SeO2. The discussion concludes with a recommendation to seek more reliable educational resources.
