Which of the following is condensation reaction?

In organic chemistry, a condensation reaction is the combination of two molecules to form a single molecule, usually with the loss of a small molecule such as water. However other molecules can also be lost, such as ammonia, ethanol, acetic acid and hydrogen sulfide. …

What is a condensation reaction in biology?

A condensation reaction joins two molecules together with the formation of a chemical bond and involves the elimination of a molecule of water. A hydrolysis reaction breaks a chemical bond between two molecules and involves the use of a water molecule.

Is condensation an addition reaction?

In a condensation reaction, two molecules combine with the loss of a smaller molecule, usually water, an alcohol or an acid. Addition reactions involve rearranging electrons of the double bonds within a monomer to form single bonds with other molecules.

What is another name of condensation reaction?

Condensation reactions are called dehydration synthesis reactions. This is because they involve the combining of molecules with the loss of water….

What is condensation polymerization reaction?

Condensation polymers are any kind of polymers formed through a condensation reaction—where molecules join together—losing small molecules as byproducts such as water or methanol. The main alternative forms of polymerization are chain polymerization and polyaddition, both of which give addition polymers.

What is addition and condensation polymerization give examples?

Common examples of addition polymerization are PVC, polyethene, Teflon etc. Common examples of condensation polymerization are nylon, bakelite, silicon, etc.

Which one of the following is condensation polymer?

Dacron is a condensation polymer. The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units.

Is PVC and additional polymer?

Polyvinyl choride is abbreviated to PVC. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene (vinyl chloride) monomer. This polymerisation reaction proceeds by a free-radical mechanism.

Is rubber a copolymer?

These are polymers made by polymerizing a mixture of two or more monomers. An example is styrene-butadiene rubber (SBR) – which is a copolymer of 1,3-butadiene and styrene which is mixed in a 3 to 1 ratio, respectively. SBR rubber was developed during World War II when important supplies of natural rubber were cut off.

What is rubber is an example of?

Rubber is an example of an elastomer type polymer, where the polymer has the ability to return to its original shape after being stretched or deformed. Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree.

How is rubber used in everyday life?

The fact that rubber can be made either soft or hard greatly increases the range of things we can use it for. Soft and stretchy latex is used in all kinds of everyday things, from pencil erasers, birthday balloons, and condoms to protective gloves, adhesives (such as sticky white PVA), and paints.

What is the properties of natural rubber?

Natural rubber has flexibility and strength, as well as impurities and vulnerability to environmental conditions and hydrocarbons. Compared to other rubbers, natural rubber is one of the most flexible types, and it’s resistant to water and certain chemicals.
