Match List-I with List-II

List-I
(A) (see structure)
(B) (see structure)
(C)

C_{17} H_{35} COO^{-} Na^{+} + Na_{2} CO_{3} +

Rosinate
(D)

CH_{3} (CH_{2})_{16} COO (CH_{2} CH_{2} O)_{n} CH_{2} CH_{2} OH

List-II
(I) Dishwashing powder
(II) Toothpaste
(III) Laundry soap
(IV) Hair conditioner

Answer: A → IV, B → II, C → III, D → I

Solution

Compound (A) is a cationic detergent (quaternary ammonium salt) used in hair conditioners because the positive charge helps it bind to negatively charged hair. Compound (B) is an anionic detergent (sodium alkyl sulfate type) used in toothpastes for its cleaning and foaming properties. Compound (C) is sodium stearate mixed with Na₂CO₃ and rosinate, which is traditional laundry soap. Compound (D) is a non-ionic detergent (polyethylene glycol ester of stearic acid) used in liquid dishwashing detergents. The correct matching is (A)-(IV), (B)-(II), (C)-(III), (D)-(I).
