Name an artificial sweetener which is derivative of sucrose.
A.Saccharine
B.Sucralose
C.Sucro Benzamide
D.Aspartame

Hint:The term sweetener means the substance which is used to increase the sweetness of food in place of sugar. We know that sucrose is a common sugar which is a disaccharide meaning a molecule consisting of two monosaccharides glucose and fructose It is also called table sugar. It is a naturally occurring carbohydrate found in many fruits and vegetables. So we will find the answer according to the structure of sucrose.

Complete step by step answer:
First we will see the structure of sucrose

Now, we will find the derivative of sucrose by studying the structure of every given compound in the options.
A.Saccharin (benzoic sulfimide) is an artificial sweetener which is basically known as benzoic sulfimide. It is 300 to 500 times sweet as compared to sucrose. The structure of Saccharin is as follows:
                 
    Here, we can see that there is a presence of benzene rings, so it is not a derivative of sucrose.
B>Sucralose: Sucralose is the trichloro derivative of sucrose. Its appearance and taste is like sugar. It is considered to be stable at cooking temperature. It is a zero calorie artificial sweetener. The structure of Sucralose is as follows:

Here, we can see that sucralose is a derivative of sucrose.

C.Sucro Benzamide: It is a benzamide derivative of sucrose. From the name itself, we can say that it involves the presence of benzene rings.
D.Aspartame: It is an artificial non saccharide sweetener having sweetness more than sucrose and is used in food and beverages.
 It is a methyl ester of aspartic acid. The structure of aspartame is as follows:
              

Therefore the correct option is B.


Note:
We have come across the two chemical substances glucose and fructose.
Glucose and fructose are the simple sugar, or we can say the monosaccharide units. These are further combined to form polysaccharides like sucrose already discussed.
These both have the same chemical formula but they differ in their structures, so they are considered as isomers.
The structure of glucose and fructose are as follows:

Glucose is often added to processed foods in form of dextrose
Fructose is a similar fruit sugar like glucose. It can show negative effects on health.
