Natural rubber is a polymer of isoprene, Yes this is the write answer.

Lets know in details,

What is Natural Rubber?

Natural rubber, also known as latex, is a type of elastomer derived from the sap or latex of certain plants, primarily the rubber tree (Hevea brasiliensis).

It is a versatile material with a wide range of applications due to its unique properties.

Production of natural rubber involves tapping the rubber tree, which involves making a diagonal incision in the bark of the tree and collecting the latex that oozes out.

The latex is a milky, sticky substance that contains rubber particles suspended in water, along with various other substances.

After collection, the latex undergoes several processing steps to convert it into usable rubber.


The process involves coagulating the latex, typically by adding an acid, which causes the rubber particles to solidify and separate from the liquid.

The resulting coagulum is then pressed to remove excess water and rolled into sheets. These sheets are then dried, smoked, and finally, shipped to manufacturers.

Natural rubber possesses excellent elasticity, high tensile strength, and good resistance to wear, tear, and abrasion.

It also exhibits low heat buildup, good electrical insulation properties, and is resistant to many chemicals. These qualities make it suitable for a wide range of applications.

One of the primary uses of natural rubber is in the manufacturing of tires and automotive products.

It is also used extensively in the production of various industrial goods, such as conveyor belts, hoses, gaskets, seals, and vibration isolators.

Additionally, natural rubber finds applications in the production of footwear, gloves, adhesives, medical products, and consumer goods like rubber bands and toys.

It’s worth noting that synthetic rubber, produced from petroleum-based chemicals, has gained significant popularity in recent decades due to its lower cost and the ability to tailor its properties to specific applications.

However, natural rubber continues to be widely used due to its unique characteristics and eco-friendliness as a renewable resource.

Natural Rubber is a polymer of

(a) Propene

The correct Answer is (C)

Yes, it is true, the natural rubber is a polymer of isoprene.

The chemical name of isoprene is 2-methyl – 1,3 butadiene it is a volatile organic compounds. it is colourless liquid.

the chemical formula of isoprene is,


Isoprene is a colourless liquid and it is unsaturated hydrocarbon. isoprene is produced by many plants and animals. isoprene polymer are the main components of natural rubber.

The chemical structure of isoprene is,

natural rubber is a polymer of

It has some important properties such as,,

formula – C5H8

molar mass – 68125/mol

Boiling point – 34.067°C

Density – 0.68 g/cm3

It is used for production of synthetic rubber such as tiers.

Natural rubber is a polymer of isoprene, because isoprene is a one type of polymer in which isoprene has elasticity property. due to this property, they returns to its original shape before deing deformed.

Natural rubber has polymer like, isoprene. Isoprene is a hydrocarbon molecule with the chemical formula C5H8.

When many isoprene units undergo polymerization, they form the polymer known as natural rubber.

The polymerization process involves the linking of multiple isoprene units together, resulting in a long-chain polymer structure.

This structure gives natural rubber its unique properties, including elasticity, flexibility, and resilience.

similarly, rubber has also elastic property, when tension are apply then rubber are band is let off and return their original position. natural rubber is also know as polyisoprene.
