Natural rubber is an example of which type of Polymer ?

Options

A. Addition polymer
B. Elastomer
C. Condensation polymer
D. None of these

Answer

To determine the type of polymer that natural rubber is an example of, we can follow these steps:

### Step 1: Identify the Monomer
Natural rubber is primarily composed of the monomer isoprene, which is chemically known as 2-methyl-1,3-butadiene.

**Hint:** Look for the basic building block (monomer) of the polymer to understand its structure.

### Step 2: Understand Polymerization
Natural rubber is formed through a process called addition polymerization. In this process, the double bonds in the isoprene molecules open up and link together to form long chains without the loss of any small molecules (by-products).

**Hint:** Addition polymerization involves the joining of monomers without the release of by-products.

### Step 3: Classify the Polymer Type
Polymers can be classified into different categories based on their properties and structure. Natural rubber is classified as an elastomer due to its elastic properties, which allow it to stretch and return to its original shape.

**Hint:** Consider the physical properties of the polymer (like elasticity) to classify it correctly.

### Step 4: Conclusion
Thus, natural rubber is an example of an addition polymer and specifically an elastomer due to its ability to stretch and recover.

**Final Answer:** Natural rubber is an example of an addition polymer and is classified as an elastomer.
