Match List-I with List-II

Choose the correct answer from the options given below.

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

The correct answer is Option (3) → (A)-(I), (B)-(II), (C)-(IV), (D)-(III)

(A) Non-electrolyte $\rightarrow$ (I) Sucrose, Urea

Non-electrolytes are substances that do not ionize at all in solution. They consist of covalent molecules like Sucrose ($C_{12}H_{22}O_{11}$) and Urea ($NH_2CONH_2$), which dissolve in water but remain as neutral molecules rather than breaking into ions.

(B) Binary electrolyte $\rightarrow$ (II) KCl, $CH_3COOH$

A binary electrolyte produces two ions per formula unit.

• $KCl$ dissociates into $K^+$ and $Cl^-$ (2 ions).
• $CH_3COOH$ partially dissociates into $CH_3COO^-$ and $H^+$ (2 ions).

(C) Quaternary electrolyte $\rightarrow$ (IV) $AlCl_3$, $K_3PO_4$

A quaternary electrolyte produces four ions per formula unit.

• $AlCl_3$ dissociates into $Al^{3+}$ and $3Cl^-$ (1 + 3 = 4 ions).
• $K_3PO_4$ dissociates into $3K^+$ and $PO_4^{3-}$ (3 + 1 = 4 ions).

(D) Ternary electrolyte $\rightarrow$ (III) $H_2SO_4$, $BaCl_2$

A ternary electrolyte produces three ions per formula unit.

• $H_2SO_4$ dissociates into $2H^+$ and $SO_4^{2-}$ (3 ions).
• $BaCl_2$ dissociates into $Ba^{2+}$ and $2Cl^-$ (3 ions).
