Among the following the correct statements are
I. Germanium exists only in traces
II. \(\mathrm{PbF}_4\) molecule is tetrahedral in shape
III. \(\mathrm{GeX}_2\) is more stable than \(\mathrm{GeX}_4\)
- A II, III only
- B I, II only
- C I, II, III
- D I, III only
Answer & Solution
Correct Answer
(B) I, II only
Step-by-step Solution
Detailed explanation
Statement I is correct as Ge and Sn exist on earth's crust in trace amounts ( \(1-2 \mathrm{ppm})\). Statement II is correct as \(\mathrm{Pb}\) belongs to group 14 and thus has four valence electrons out of which all four are used to make the four \(\mathrm{Pb}-\mathrm{F}\)…
