A.RAMA NAGESWARARAO · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Surface Chemistry (Detergents and their uses)
	**Related Topics**: Soaps, Micelles, Emulsification, Cleaning agents
	**Prerequisites**: Basic understanding of detergents and their applications.
## SOLUTION PATHWAY
**Given Information**:
	The question asks for the use of Sodium dodecyl benzene sulphonate.
**Method & Steps**:
	1. **Identify the nature of the compound**: Sodium dodecyl benzene sulphonate is an anionic surfactant.
		Reasoning: Its chemical structure contains a hydrophobic (water-repelling) tail and a hydrophilic (water-attracting) head, allowing it to interact with both grease and water.
	2. **Relate its properties to its use**: This property of interacting with both grease and water makes it effective in removing dirt and grease.
		Working: The hydrophobic tail attaches to grease and oil, while the hydrophilic head interacts with water. This allows the grease and oil to be lifted and washed away.
		Key Point: This mechanism is the fundamental principle behind the cleaning action of detergents.
	3. **Determine the application based on its cleaning properties**:  Substances with these properties are used as detergents.
		Result: Sodium dodecyl benzene sulphonate is used as a detergent.
		Verification: This aligns with the common use of alkylbenzene sulfonates as detergents in various cleaning products.
## OPTION ANALYSIS
[A] ✓: Detergent - Sodium dodecyl benzene sulphonate is a common ingredient in many laundry detergents, dishwashing liquids, and other cleaning agents due to its excellent surfactant properties.
[B] :x: Antiseptic - Antiseptics are substances that inhibit the growth and reproduction of microorganisms on living tissue. While some detergents might have mild antiseptic properties, the primary function of sodium dodecyl benzene sulphonate is cleaning, not disinfection.
[C] :x: Analgesic - Analgesics are pain relievers. Sodium dodecyl benzene sulphonate has no pain-relieving properties.
[D] :x: Disinfectant - Disinfectants are substances that kill microorganisms on non-living surfaces. While some detergents can have disinfectant properties, the primary role of sodium dodecyl benzene sulphonate is as a cleaning agent.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing detergents with disinfectants: While some detergents might have disinfectant properties, their primary function is cleaning.
			How to avoid: Understand the specific definitions of detergents and disinfectants.
		2. Assuming all cleaning agents are detergents: Soaps are another type of cleaning agent, but they differ from detergents in their chemical composition.
			How to avoid: Learn about the different types of cleaning agents and their respective properties.
	**Quick Tips**:
		1. Remember the suffix '-sulfonate' often indicates a detergent.
		2. Associate 'sodium dodecyl benzene sulphonate' with common cleaning products like laundry detergents and dish soaps.
