Question

Which of the following oxoacids of sulphur contains "S" in two different oxidation states?

Options
  1. a

    H2S2O3\mathrm{H_2S_2O_3}

    ✓
  2. b

    H2S2O6\mathrm{H_2S_2O_6}

  3. c

    H2S2O7\mathrm{H_2S_2O_7}

  4. d

    H2S2O8\mathrm{H_2S_2O_8}

Correct Answera

H2S2O3\mathrm{H_2S_2O_3}

Detailed Solution

Strategy: Correlate noble gas formulas with their three-dimensional shapes.

Step 1: Structural Mapping

  • \ceXeF6\ce{XeF6}: Distorted Octahedral.
  • \ceXeO3\ce{XeO3}: Pyramidal.
  • \ceXeOF4\ce{XeOF4}: Square Pyramidal.
  • \ceXeF4\ce{XeF4}: Square Planar.

Step 2: Conclusion Matching each formula to its shape identifies the correct set.

Answer: (Option) [a] [Correct matching set]\boxed{\text{Answer: (Option) [a] [Correct matching set]}}
