Identifying Polymeric Materials

This question requires identifying which of the given substances are polymeric materials. Polymers are large molecules, often called macromolecules, composed of many repeating subunits known as monomers.

Analysis of Options

(i) Glucose

Glucose is a simple sugar with the chemical formula $C_6H_{12}O_6$. It is a monosaccharide, meaning it consists of a single sugar unit. Glucose serves as a monomer that can be linked together to form larger carbohydrate polymers like cellulose and starch. Therefore, glucose itself is not a polymer.

(ii) Cellulose

Cellulose is a complex carbohydrate and a major structural component of the cell walls of plants. It is a polysaccharide, which is a type of polymer. Cellulose is formed by the linkage of many glucose units. Thus, cellulose is a polymeric material.

(iii) Starch

Starch is another important carbohydrate found in plants, serving as a form of energy storage. Like cellulose, starch is a polysaccharide and therefore a polymer. It is also composed of repeating glucose units, primarily in two forms: amylose and amylopectin. Thus, starch is a polymeric material.

(iv) PVC (Polyvinyl Chloride)

Polyvinyl Chloride, commonly known as PVC, is a widely used synthetic plastic material. It is a polymer formed by the polymerization of vinyl chloride monomers. PVC is extensively used in construction, electronics, and various consumer goods. Thus, PVC is a polymeric material.

Conclusion

Based on the analysis:

• Glucose is a monomer.
• Cellulose is a polymer.
• Starch is a polymer.
• PVC is a polymer.

Therefore, the polymeric materials among the given options are Cellulose, Starch, and PVC.
