Q27 / 160 · TS EAMCET 2025 (03 May Shift 2) · Chemistry

Which one of the orders is correctly matched with the property mentioned against it?

  • A
    $\mathrm{H}_2 \mathrm{~S} < \mathrm{H}_2 \mathrm{O} < \mathrm{H}_2 \mathrm{Se} < \mathrm{H}_2 \mathrm{Te} \quad$ (Boiling point)
  • Correct answer
    B
    $\mathrm{N}_2 \mathrm{O} < \mathrm{NO} < \mathrm{N}_2 \mathrm{O}_3 < \mathrm{N}_2 \mathrm{O}_4 < \mathrm{N}_2 \mathrm{O}_5$ (Acidic nature)
  • C
    $\mathrm{HI} < \mathrm{HCl} < \mathrm{HBr} < \mathrm{HF}$ (Acidic nature)
  • D
    $\mathrm{H}_2 \mathrm{O} < \mathrm{H}_2 \mathrm{~S} < \mathrm{H}_2 \mathrm{Se} < \mathrm{H}_2 \mathrm{Te} \quad$ (Bond angle)

Hence, the correct answer is option: 'B'.
