What are the bonds that are broken in the combustion of ethene?
The bonds that break in this reaction are one C=C bond and four C-H bonds.
Is ethene gas a single bond?
No, ethylene (ethene) has a carbon-carbon double bond, in addition to four other single bonds between carbon and hydrogen.
Why is ethene regarded as unsaturated hydrocarbon?
As ethene contains double bond it is considered as unsaturated hydrocarbon. Note-hydrocarbon is said to saturated when it contain C-C single bond and hydrocarbon is said to unsaturated when it has carbon carbon double or triple bonds
What is the active ingredient in polymer?
Polymer is not a substance. It is a term applied to something that has 'many links' For example Polyethene is ethene connected to ethene connected to ethene and so on. So if something is a polymer it basically mean there is many of them (e.g polysaccharides= many sugars)
What type of chemical bond is C2H4?
Ethene has C=C and C-H covalent bonds. It is easily depicted using a dot and cross diagram.
What does ethene have that polyethene does not?
double bonds
How many types of bonds are present ethene?
Ethene (C2H4) has 2 bonds between the 2 carbon atoms and each carbon atom shares 2 electrons from 2 Hydrogen atoms.
How many covalent bonds in ethylene?
A molecule of ethene contains 6 covalent bonds, namely 5 sigma bonds and a pi bond.
What contains two double bonds?
Ethene
How many covalent bonds are there in ethane?
Ethene is C2H4. There 6 bonds, 4 single bonds and one double bonds or alternativelly 5 sigma bonds and one pi bond
What are the bonds that are broken in the combustion of ethene?
The bonds that break in this reaction are one C=C bond and four C-H bonds.
Is ethene gas a single bond?
No, ethylene (ethene) has a carbon-carbon double bond, in addition to four other single bonds between carbon and hydrogen.
Can anyone give me some examples of a substance whose molecules contain pi-bonds?
Ethene and ethyne.
Why is ethene regarded as unsaturated hydrocarbon?
As ethene contains double bond it is considered as unsaturated hydrocarbon. Note-hydrocarbon is said to saturated when it contain C-C single bond and hydrocarbon is said to unsaturated when it has carbon carbon double or triple bonds
How is plastic made today?
Plastic is poly-ethylene. it is made by the polymerisation of ethylene or ethene and they add some chemicals to strengthen the bonds

How did polyethylene form?
It forms through addition polymerisation. The double bonds in ethene break to form a long continuous chain ( a polymer) which is polyethylene.
