All the compounds listed in Column-I react with water. Match the result of the respective reactions with the appropriate option(s) listed in Column-II (each Column-I entry may match more than one Column-II entry).

Column-I: (A) (CH3)2SiCl2 (B) XeF4 (C) Cl2 (D) VCl5 Column-II: (p) Hydrogen halide formation (q) Redox reaction (r) Reacts with glass (s) Polymerization (t) O2 formation

Answer: (A)

Solution

(A) Hydrolysis of (CH3)2SiCl2 gives (CH3)2Si(OH)2 and HCl; the diol then undergoes condensation to form silicone polymers — so this matches both "hydrogen halide formation" (p) and "polymerization" (s). (B) XeF4 hydrolyses by disproportionation: 6XeF4 + 12H2O → 4Xe + 2XeO3 + 24HF + 3O2 — this releases HF ("hydrogen
