Worked practice questions

Reaction of XeF₂ with water:

  1. Inert
  2. XeF₂ + 2 H₂O → Xe(OH)₂
  3. No reaction
  4. XeF₂ + H₂O → Xe + HF + O₂ (disproportionation/hydrolysis)
Show answer and solution

Correct answer: D. XeF₂ + H₂O → Xe + HF + O₂ (disproportionation/hydrolysis)

XeF₂ slowly hydrolyzes: 2 XeF₂ + 2 H₂O → 2 Xe + 4 HF + O₂. Xenon fluorides are powerful oxidizers. XeF₄, XeF₆ also exist. Demonstrates that even 'inert' noble gases form compounds under right conditions.

As per your syllabus, in IUPAC systematic nomenclature for Z > 100, what are the digit roots for 1, 2 and 0 respectively?

  1. un (u), bi (b), nil (n)
  2. mono (m), di (d), null (nl)
  3. ek (e), do (d), shun (s)
  4. one (o), two (t), zero (z)
Show answer and solution

Correct answer: A. un (u), bi (b), nil (n)

As per your syllabus, 0=nil(n), 1=un(u), 2=bi(b), …, 9=enn(e). Suffix '-ium' added.
