Bakelite is formed through a polycondensation reaction, which is a type of step-growth polymerization, rather than strictly anionic or cationic polymerization. It is created from the reaction of phenol and formaldehyde, typically in the presence of a catalyst, leading to a thermosetting plastic. The process involves the formation of cross-linked structures, characteristic of Bakelite, during the curing stage.
What else can I help you with?
What is the process in which a macromolecule formed when a monomers join together?
This is termed polymerisation. Poly is greek for many.
What is an arenium ion?
An arenium ion is a cation formed by the addition of a proton or other cationic species to an arene.
How bakelite is formed from phenol?
Bakelite is formed through a polymerization process involving phenol and formaldehyde. In the presence of a catalyst, phenol reacts with formaldehyde to create a series of cross-linked polymer chains, resulting in a thermosetting plastic. This process can be initiated under heat and pressure, leading to a hard, durable material. The final product is characterized by its heat resistance and electrical insulating properties.
What is footlike cytoplasmic extensions?
Footlike cytoplasmic extensions, also known as pseudopodia, are temporary protrusions of the cell membrane in amoeba and other protists. They are involved in movement and feeding by extending and retracting in a flowing manner. Pseudopodia help the cell to capture food particles and move towards favorable environments.
What is adition polymerisation?
it is the fusing together of monomers and hydrocarbons by using heat.addition to above answere.it is the addition of monomer molecules to form bigger particle which is called polymer.the reaction is carried out by heat, and catalyst like potassium per sulphate,cumene peroxide,s.m.b.s.etc.as well as emusifier is must for emulsion polymerisation.the molecular wt. of polymer is much more than monomer.
What is the complex salts?
A complex salt is the salt of one or more complex ions, the complex part can be cationic or anionic or both such as Ca3[Co(Cl)6]2 the complex part behaves as an anion [Co(NH3)6]Cl3 the complex part behaves as a cation [Co(NH3)6][Co(Cl)6] the both of the anionic and cationic parts of the are formed by complex ions
Why cationic molecular ions are greater then anionic one?
Cationic molecular ions are usually smaller than their corresponding anionic ions because they have lost an electron and thus have a higher effective nuclear charge that pulls the remaining electrons closer to the nucleus, resulting in a smaller size. Additionally, cationic ions often have a stable electron configuration (e.g., a noble gas configuration) that contributes to their smaller size.

Is Bakelite thermosetting or thermoplastic?
Bakelite is a thermosetting plastic, meaning that once it is formed and cured, it cannot be melted and reshaped like a thermoplastic. This property makes Bakelite ideal for applications requiring heat resistance and durability.
What is an arenium ion?
An arenium ion is a cation formed by the addition of a proton or other cationic species to an arene.
What is an arenonium ion?
An arenonium ion is an obsolete term for an arenium ion, a cation formed by the addition of a proton or other cationic species to an arene.
What is the formula of the hydride formed by helium?
The formula of the hydride formed by helium is HeH+. It's a cationic species known as the helium hydride ion, which is formed when helium reacts with hydrogen ions in very low-temperature environments such as interstellar space.
What is the structure of bakelite?
Bakelite is a thermosetting plastic made from the polymerization of phenol and formaldehyde. The structure consists of a three-dimensional network of cross-linked chains, giving it its rigid and heat-resistant properties.
How bakelite is formed from phenol?
Bakelite is formed through a polymerization process involving phenol and formaldehyde. In the presence of a catalyst, phenol reacts with formaldehyde to create a series of cross-linked polymer chains, resulting in a thermosetting plastic.

What are macromolescules?
Macromolecules are giant molecules that are formed when thousands of smaller units of identical molecules are joined together. This process of joining together smaller identical units into a large macromolecules (polymer) is called polymerisation.
When was bakelite invented?
Bakelite is used in making electrical appliances because it has very good electrical insulating properties.
