(
)
| Column I | Column II | ||
| A. | Mg in solid state | 1. | P-type semiconductor |
| B. | MgCl_2 in molten state | 2. | n-type semiconductor |
| C. | Silicon with phosphorus | 3. | Electrolytic conductor |
| D. | Germanium with boron | 4. | Electronic conductors |
Options
- AA-4 B-3 C-2 D-1
- BA-3 B-4 C-1 D-2
- CA-3 B-4 C-2 D-1
- DA-4 B-2 C-3 D-1
Correct answer
A. A-4 B-3 C-2 D-1
Step-by-step solution
A. (\rightarrow(4)) B. (\rightarrow(3)) C. (\rightarrow(2)) D. (\rightarrow(1))
A. Mg in solid state show electronic conductivity due to presence of free electrons hence they are known as electronic conductors.
B. (\mathrm{MgCl}_2) in molten state show electrolytic conductivity due to presence of electrolytes in molten state.
C.Silicon doped with phosphorus contain one extra electron due to which it shows conductivity under the influence of electric field known as p-type semiconductor.
D. Germanium doped with boron contain one hole due to which it shows conductivity under the influence of electric field and known as n-type semiconductor.
