JEE MAIN - Chemistry (2021 - 31st August Evening Shift - No. 5)
Match List - I with List - II
Choose the most appropriate answer from the options given below :
| List - I (Parmeter) |
List - II (Unit) |
||
|---|---|---|---|
| (a) | Cell constant | (i) | $$S\,c{m^2}mo{l^{ - 1}}$$ |
| (b) | Molar conductivity | (ii) | Dimensionless |
| (c) | Conductivity | (iii) | $${m^{ - 1}}$$ |
| (d) | Degree of dissociation of electrolyte | (iv) | $${\Omega ^{ - 1}}{m^{ - 1}}$$ |
Choose the most appropriate answer from the options given below :
(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
(a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
(a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)
(a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
Explanation
Cell constant = $$\left( {{l \over A}} \right)$$ $$\Rightarrow$$ Units = m$$-$$1
Molar conductivity ($$\Lambda $$m) $$\Rightarrow$$ Units = Sm2 mole$$-$$1
Conductivity (K) $$\Rightarrow$$ Units = S m$$-$$1
Degree of dissociation ($$\alpha$$ $$\to$$ Dimensionless
$$\therefore$$ (a) - (iii), (b) - (i), (c) - (iv), (d) - (ii)
Molar conductivity ($$\Lambda $$m) $$\Rightarrow$$ Units = Sm2 mole$$-$$1
Conductivity (K) $$\Rightarrow$$ Units = S m$$-$$1
Degree of dissociation ($$\alpha$$ $$\to$$ Dimensionless
$$\therefore$$ (a) - (iii), (b) - (i), (c) - (iv), (d) - (ii)
