The Correct Option is D
Solution and Explanation
Concept:
Detergents are surface-active agents used in cleaning and conditioning.
• Toothpastes commonly contain anionic detergents like sodium lauryl sulfate
• Hair conditioners use cationic detergents like quaternary ammonium salts
Step 1: Identify detergent X (toothpaste). Anionic detergent: \[ CH_3(CH_2)_{10}CH_2OSO_3Na \] This is sodium lauryl sulfate, commonly used in toothpaste. Thus X identified.
Step 2: Identify detergent Y (hair conditioner). Cationic surfactants like quaternary ammonium salts are used in conditioners. \[ CH_3(CH_2)_{15}N(CH_3)_3Br \] This helps in reducing static and improving hair smoothness. Thus Y identified.
Step 3: Final answer. \[ X=CH_3(CH_2)_{10}CH_2OSO_3Na,\quad Y=CH_3(CH_2)_{15}N(CH_3)_3Br \] Hence option (D).
