Match the following characteristics of transition metals given in Column I with the examples listed in Column II
| S.No. | Characteristic properties | S.No. | Examples |
|---|---|---|---|
| W | Chemically inert, non-stoichiometric compound | A | \(WO_3\) |
| X | Higher oxidation states are more stable | B | \(TiCl_4\) |
| Y | Due to inert pair effect, lower oxidation state is more stable | C | \(Mn_4N\) |
| Z | Colourless compound of transition metal | D | \(SnCl_2\) |
- A \(\mathrm{W}=\mathrm{C} \quad \mathrm{X}=\mathrm{A} \quad \mathrm{Y}=\mathrm{D} \quad \mathrm{Z}=\mathrm{B}\)
- B \(\mathrm{W}=\mathrm{C} \quad \mathrm{X}=\mathrm{D} \quad \mathrm{Y}=\mathrm{A} \quad \mathrm{Z}=\mathrm{B}\)
- C \(\mathrm{W}=\mathrm{A} \quad \mathrm{X}=\mathrm{D} \quad \mathrm{Y}=\mathrm{C} \quad \mathrm{Z}=\mathrm{B}\)
- D \(\mathrm{W}=\mathrm{B} \quad \mathrm{X}=\mathrm{C} \quad \mathrm{Y}=\mathrm{D} \quad \mathrm{Z}=\mathrm{A}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{W}=\mathrm{C} \quad \mathrm{X}=\mathrm{A} \quad \mathrm{Y}=\mathrm{D} \quad \mathrm{Z}=\mathrm{B}\)
Step-by-step Solution
Detailed explanation
W: Chemically inert, non-stoichiometric compound. Interstitial compounds like \(\mathrm{Mn_4N}\) are non-stoichiometric and often chemically inert. Thus, W matches with C. X: Higher oxidation states are more stable. In the case of \(\mathrm{WO_3}\), tungsten is in its highest…
