SO₂ + PCl₅ → (X) (pyramidal molecule) + (Y) (non-planar molecule) Select the INCORRECT statement(s) about the products (X) and (Y) formed in the above reaction.

TestHub · Accepted Answer

SO₂ + PCl₅ → SOCl₂ (X, pyramidal) + POCl₃ (Y, tetrahedral). Both SOCl₂ (lone pair on S) and POCl₃ (P=O dipole) are polar, so (A) is true and (B) is incorrect. Hydrolysis: SOCl₂ + H₂O → SO₂ + 2HCl (dibasic H₂SO₃ chemistry) but POCl₃ + 3H₂O → H₃PO₄ (TRIBASIC) + 3HCl, so (C) is incorrect. SOCl₂ is the standard chlorinating agent (converts -OH/-COOH to -Cl), so (D) is true.
