Because of the mechanism of addition polymerization;
In addition polymerization the pi-bond of a molecule with a double bond (e.g. ethene) is broken by attatchment of a radical (a molecule with a lone electron) to the molecule with the double bond:
one of the two electrons that formed the double bond pairs up with the single electron from the radical so the other electron from the double bond becomes a lone electron himself; and so it continues until two radicals meet each other.
So you need to have a double bond in order to have this kind of polymerization;
(there are other kinds of polymerization of molecules whitch have a functional group but ethane nor ethene has these so it doesn't apply to them.)
What else can I help you with?
What polymer is formed when lots of ethane molecules are joined together?
Polyethylene is the polymer formed when lots of ethane molecules are joined together through a process called polymerization. It is a widely used plastic material in various applications due to its versatility and flexibility.
What alkane is formed when ethene reacts with hydrogen?
addition reactions. I was looking up the same question and found it!!!
A molecule of ethane and a molecule of ethene both have the same?
Both ethane and ethene have the same number of carbon atoms per molecule, which is two. However, the difference lies in the type of bonds between the carbon atoms - ethane has single bonds, while ethene has a double bond.
Which of the following is most reactive A. ethane B. ethene C. ethyne D. they are all equally reactive?
Ethyne is most reactive where as ethane is least.
Ethene differs from ethane in that it has a?
double bond between carbon atoms.
How does the structure of ethene compare to the structure of ethane?
Both ethene and ethane contain two carbons. Ethene has a double bond between its two carbons while ethane has a single bond. Because of this, ethane contains six hydrogen atoms, but ethene only contains four.
What chemical reactions do both ethane and ethene undergo?
Both ethane and ethene can undergo combustion reactions to produce carbon dioxide and water. They can also undergo halogenation reactions with halogens such as chlorine or bromine to form halogenated hydrocarbons. Additionally, they can undergo polymerization reactions to form longer chain hydrocarbons or polymers.
What makes a satured hydrocarbon from an unsaturadted hydocarbon?
It is done by the process of Hydrogenation. Example:- C2H4 + H2 ---------> C2H6 Thus, ethene undergoes hydrogenation to form ethane
What polymer is formed when lots of ethane molecules are joined together?
Polyethylene is the polymer formed when lots of ethane molecules are joined together through a process called polymerization. It is a widely used plastic material in various applications due to its versatility and flexibility.
What type of chemical reaction is involved in the synthesis of the polymer polyethylene from ethene monomers?
The synthesis of polyethylene from ethene monomers involves a polymerization reaction, specifically addition polymerization. In this process, ethene (an alkene) undergoes a reaction where the double bonds between carbon atoms are broken, allowing the monomers to link together and form long chains of polyethylene. This reaction typically requires catalysts and can occur under heat and pressure.
What alkane is formed when ethene reacts with hydrogen?
addition reactions. I was looking up the same question and found it!!!
A molecule of ethane and a molecule of ethene both have the same?
Both ethane and ethene have the same number of carbon atoms per molecule, which is two. However, the difference lies in the type of bonds between the carbon atoms - ethane has single bonds, while ethene has a double bond.
What is the raw material used to obtain ethane by hydrogenation?
ethene
What is mechanism of copolymers of ethylene and propylene?
This the simultaneous polymerization of ethene and propylene.
If Polyethylene is a polymer made from ethane molecules that have been joined together what is ethane in this polymer?
Ethane is a simple hydrocarbon molecule consisting of two carbon atoms and six hydrogen atoms (C2H6). In the context of polyethylene, ethane serves as the monomer that undergoes polymerization, a chemical process where multiple ethane molecules are linked together to form long chains of polyethylene. Thus, ethane acts as the building block from which the larger polymer structure is created.
Which of the following is most reactive A. ethane B. ethene C. ethyne D. they are all equally reactive?
Ethyne is most reactive where as ethane is least.
What happens to each ethene molecule when it becomes polyethene?
Each ethene molecule undergoes a polymerization process where multiple ethene molecules join together to form a long chain polymer known as polyethylene. This polymer has a linear or branched structure depending on the polymerization conditions, resulting in a material with improved strength, flexibility, and chemical resistance compared to individual ethene molecules.
