Match List-I and List-II.
List-I (Chemical compound)
A. Sucralose
B. Glyceryl ester of stearic acid

Q: Why is sucralose considered a zero-calorie sweetener if it's made from sugar?

Sucralose is made by replacing three hydroxyl groups in a sugar molecule with chlorine atoms. This modification prevents the body's enzymes from breaking it down, meaning it passes through the digestive system without providing any calories.

Q: What is the difference between a soap and a synthetic detergent?

Soaps are sodium or potassium salts of long-chain fatty acids (like stearic acid), whereas synthetic detergents are usually sodium salts of long-chain alkyl sulfates or sulfonates. Detergents work better in hard water because they don't form insoluble scum like soaps do.

Q: How does sodium benzoate preserve food?

Sodium benzoate dissolves in water to form benzoic acid, which is the active preserving agent. It enters the cells of microorganisms and lowers their internal pH, which inhibits their enzymes and prevents them from growing and spoiling the food.

Q: Why is bithionol specifically added to soaps?

Bithionol is an antibacterial agent. When added to soaps, it helps kill or inhibit the bacteria on the skin that break down sweat and organic matter into foul-smelling compounds, thereby acting as an effective deodorant and antiseptic.

Q: Are artificial sweeteners like sucralose safe for consumption?

Yes, sucralose and several other artificial sweeteners are approved by food safety authorities worldwide (like the FDA and WHO) for consumption within acceptable daily intake limits. They are a safe alternative for people managing their calorie or sugar intake.

Sigma Percentile · Accepted Answer

The world of chemistry extends far beyond the laboratory; it is deeply embedded in our daily lives, from the food we eat to the soaps we use. This problem is a classic example of "Chemistry in Everyday Life," where we are asked to match common chemical compounds with their practical applications. Let's break down each compound and understand its role.

### Sucralose: The Sweet Deception
Imagine enjoying a sweet dessert without worrying about the calories. That's the magic of **Sucralose**. It is an artificial sweetener that is synthesized from sugar but is modified so that our bodies cannot metabolize it for energy.

Because it provides the sweetness of sugar with zero or very low calories, it is widely used in diet drinks, sugar-free candies, and baked goods. Therefore, Sucralose (A) perfectly matches with Artificial sweetener (2).

### Glyceryl Ester of Stearic Acid: The Cleaning Agent
Next, we have the **Glyceryl ester of stearic acid**. Stearic acid is a long-chain saturated fatty acid commonly found in animal and vegetable fats.

When stearic acid reacts with glycerol, it forms esters that are fundamental in the production of soaps and synthetic detergents. These molecules have a unique structure with a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail, allowing them to trap dirt and oil. Thus, Glyceryl ester of stearic acid (B) matches with Synthetic detergent (1).

### Sodium Benzoate: The Guardian of Food
Have you ever wondered how packed juices, jams, and pickles stay fresh for months? The secret ingredient is often **Sodium benzoate**.

Food is constantly under threat from aerial oxidation, moisture, and microbial growth (like bacteria and fungi). Sodium benzoate acts as a highly effective food preservative. Its aromatic ring helps stabilize free radicals, preventing the oxidation of food, while also creating an acidic environment that inhibits microbial growth. Hence, Sodium benzoate (C) matches with Food preservative (4).

### Bithionol: The Odor Fighter
Finally, let's talk about **Bithionol**. Throughout the day, organic matter on our skin is broken down by bacteria, which produces body odor.

To combat this, Bithionol is added to medicated soaps. It possesses strong antiseptic properties that prevent the bacterial decomposition of organic matter on the skin, keeping us fresh and odor-free. Therefore, Bithionol (D) matches with Antiseptic (3).

### The Final Verdict
By analyzing the everyday applications of these chemicals, we have successfully decoded the matches:
- **A $\rightarrow$ 2**
- **B $\rightarrow$ 1**
- **C $\rightarrow$ 4**
- **D $\rightarrow$ 3**

This sequence corresponds exactly to option (b). Understanding these compounds not only helps in exams but also makes us more aware of the ingredients in the products we use daily!
