Among the following which one is homopolymers
Neoprene
Polymers are large molecules made up of repeating smaller units called monomers. Depending on the type of monomers used, polymers can be classified into different categories. Two main types are homopolymers and copolymers.
A homopolymer is a polymer formed from only one type of monomer. All the repeating units in the polymer chain are identical. For example, polyethylene is a homopolymer made from repeating ethylene units.
A copolymer, on the other hand, is formed from two or more different types of monomers. The repeating units in a copolymer chain are not all the same. Examples include nylon 6,6 and Bakelite.
Let's examine each option to determine whether it is a homopolymer or a copolymer.
Bakelite is a polymer formed by the reaction between phenol and formaldehyde. Since it is made from two different monomers (phenol and formaldehyde), Bakelite is a copolymer.
Terylene, also known as Polyethylene Terephthalate (PET), is synthesized from two monomers: ethylene glycol and terephthalic acid. Because it uses two distinct types of monomers, Terylene is classified as a copolymer.
Nylon 6,6 is a synthetic polymer produced by the reaction between hexamethylenediamine and adipic acid. These are two different monomers, making Nylon 6,6 a copolymer.
Neoprene is a synthetic rubber. Its chemical name is polychloroprene. It is formed by the polymerization of a single type of monomer called chloroprene (\(CH_2=CCl-CH=CH_2\)). Since only one type of monomer unit repeats to form the polymer chain, Neoprene is a homopolymer.
Based on the analysis of the monomers that make up each polymer, we can identify the homopolymer among the given options.
| Polymer | Monomer(s) | Type of Polymer |
|---|---|---|
| Bakelite | Phenol, Formaldehyde | Copolymer |
| Terylene | Ethylene Glycol, Terephthalic Acid | Copolymer |
| Nylon 6,6 | Hexamethylenediamine, Adipic Acid | Copolymer |
| Neoprene | Chloroprene | Homopolymer |
As shown in the table, Neoprene is the only polymer among the options that is formed from a single type of monomer (chloroprene). Therefore, Neoprene is the homopolymer.
Understanding the difference between a homopolymer and a copolymer is fundamental in polymer chemistry. A homopolymer like Neoprene has a simpler structure compared to a copolymer.
