Question

Match List-I with List-II.

• A. (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
• B. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
• C. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
• D. (A)-(IV), (B)-(III), (C)-(II), (D)-(I)

Hint:

Conductance is measured in Siemens (S), whereas resistance is measured in Ohm (\(\Omega\)). They are reciprocals of each other.

Answer 1

The Correct Option is B

Concept: Different electrochemical quantities possess characteristic SI and practical units.

Step 1: Recall the unit of conductivity.
Conductivity measures the conducting ability of a solution. Its common unit is \[ \text{S cm}^{-1} \] Hence \[ (A)\rightarrow(III) \]

Step 2: Recall the unit of molar conductivity.
Molar conductivity is conductivity per mole of electrolyte. \[ \text{S cm}^{2}\text{ mol}^{-1} \] Therefore \[ (B)\rightarrow(IV) \]

Step 3: Recall the unit of resistance.
Resistance is measured in ohm. \[ \Omega \] Therefore \[ (C)\rightarrow(I) \]

Step 4: Recall the unit of conductance.
Conductance is reciprocal of resistance. \[ \text{S} \] Hence \[ (D)\rightarrow(II) \] Thus \[ (A)-(III),\ (B)-(IV),\ (C)-(I),\ (D)-(II) \]
