Question
Inorganic; I understand there are a lot of components to this question set, but if you do take time to begin to answer, please be thorough and answer all parts. Thanks a lot!
1.Use Slater's Rules to explain which electron is lost, first, second, third, and fourth when tungsten is oxidized from neutral metal to tungsten(IV). SHOW YOUR WORK.
2.WHat is the formula of the highest oxide of tungsten (VI)? Name it. What would you expect pkb of this oxide to be? What shape would you expect this ion/molecule to have. SHOW YOUR WORK
3. If you reduced the species from #2 from tungsten (VI) to tungsten(IV) but kept the same number of oxo groups, would you expect the geometery to change. EXPLAIN YOUR ANSWERS WITH EXPLICIT CALCULATIONS
Explanation / Answer
1. Slater's rules, the electron experincing less Zeffec will be lost first followed by step by step.
From W, electron is lost in the order of,
1st electron from 6s,
2nd electron also from 6s,
3rd electron from 5d,
and 4th electron is also from 5d
2. Tungsten(VI) oxide is WO3
Its name is Tungsten trioxide or tungsten(VI)oxide or Tungstic anhydride
Its structure is temperature dependant, it is in monoclinic shape at 17 - 330 degree C
