| Column I | Column II | |||
| [Atomic masses (M)] | (% composition of heavier isotrope) | |||
| Isotope-II | Isotope-II | Average | ||
| (A) | (z-1) | (z+3) | z | (P) 25 \% by moles |
| (B) | (z+1) | (z+3) | (z+2) | (Q) 50 \% by moles |
| (C) | z | 3 z | 2 z | (R) \% by mass dependent on z |
| (D) | (z-1) | (z+1) | z | (S) 75 \% by mass |
Options
- A((A) \rightarrow(P, S),(B) \rightarrow(R, Q),(C) \rightarrow(Q),(D) \rightarrow(P))
- B((\mathrm{A}) \rightarrow(\mathrm{P}),(\mathrm{B}) \rightarrow(\mathrm{R}),(\mathrm{C}) \rightarrow(\mathrm{S}),(\mathrm{D}) \rightarrow(\mathrm{Q}))
- C(A) (\rightarrow(\mathrm{R}, \mathrm{S}),(\mathrm{B}) \rightarrow(\mathrm{S}),(\mathrm{C}) \rightarrow(\mathrm{P}),(\mathrm{D}) \rightarrow(\mathrm{Q}, \mathrm{P}))
- D((\mathrm{A}) \rightarrow(\mathrm{P}, \mathrm{R}),(\mathrm{B}) \rightarrow(\mathrm{Q}, \mathrm{R}),(\mathrm{C}) \rightarrow(\mathrm{S}, \mathrm{Q}),(\mathrm{D}) \rightarrow(\mathrm{Q}, \mathrm{R}))
Correct answer
D. ((\mathrm{A}) \rightarrow(\mathrm{P}, \mathrm{R}),(\mathrm{B}) \rightarrow(\mathrm{Q}, \mathrm{R}),(\mathrm{C}) \rightarrow(\mathrm{S}, \mathrm{Q}),(\mathrm{D}) \rightarrow(\mathrm{Q}, \mathrm{R}))
