Question

Match List - I with List - II.

Choose the most appropriate match from the options given below:

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

Hint:

- Calgon → Water softener - Soap → Sodium salts of fatty acids - Cryolite → Used in aluminium extraction - $C_{12}H_{22}O_{11}$ → Disaccharides (like sucrose, cellobiose)

Answer 1

The Correct Option is B

Concept: We identify each compound based on its chemical formula and common usage/name.

Step 1: Match each compound.

• $Na_6P_6O_{18}$ → Calgon (used in water softening) → A-III
• $C_{17}H_{35}COONa$ → Soap (sodium stearate) → B-IV
• $C_{12}H_{22}O_{11}$ → Cellobiose (a disaccharide) → C-I
• $Na_3AlF_6$ → Cryolite → D-II

Step 2: Write the correct matching.
\[ A\text{-III},\quad B\text{-IV},\quad C\text{-I},\quad D\text{-II} \]

Step 3: Final conclusion.
Thus, the correct option is: \[ (B) \]
