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.
Which compound contains a longer C-C bond benzene or ethene?
c-c bond length in benzene is 1.397 angston and that of ethene is 1.34 angston structure of benzene is a resonance hybrid, therefore all the c-c bond lengths are equal but different from those in alkanes,alkenes, and alkynes.
Is ethyne a unsaturated hyrocarbon?
Yes, any hydrocarbon with C & H with a double or triple bond is unsaturated
How do you distinguish between ethane and ethene?
Ethane has two carbon atoms and six hydrogen atoms (C2H6). It is a flammable gas and is a saturated molecule, meaning that each carbon atom has four bonds linked to 4 other atoms. Methane (CH4), propane (C3H8) and butane (C4H10) are similar molecules and all are flammable gases. Ethene has two carbon atoms and four hydrogen atoms (C2H4). It is also a gas but it is an unsaturated molecule: the two carbon atoms are linked by a double bond. Ethene molecules can join together into a single, long molecule. The result is a string of carbon atoms that each have two hydrogen atoms attached and are also linked to two other carbon atoms. This is polythene or polyethelene, a simple polymer that is used for plastic bags among other things. The ability to form into long chains is due to the double bond between the carbon atoms in the ethene molecule.
Why the reaction of ethene with bromine called an addition reaction?
Br2 + C2H4 → C2H4Br2 ORBr2 + CH2=CH2 → BrCH2CH2BrThe name of the reaction is pretty intuitive. Ethene's double bond is broken which leaves room for bromine to be added to form dibromoethane.
Is ethene ionic or covalent?
Covalent, ethene has a double bond, C2H4
Ethene differs from ethane in that it has a?
double bond
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 unsaturated carbon?
Because there is a double bond
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.
Why is no number used in the names ethene and propene?
ethene: CH2=Ch2 propene: CH2=CH3CH There is nowhere else to place a double bond! (C=C) No number is used in the names ethene and propene because the number would be useless as the double bond is located at carbon "1"
Why does polyethene not react in the same way with bromine water as ethene?
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
Which compound contains a longer C-C bond benzene or ethene?
c-c bond length in benzene is 1.397 angston and that of ethene is 1.34 angston structure of benzene is a resonance hybrid, therefore all the c-c bond lengths are equal but different from those in alkanes,alkenes, and alkynes.
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
Why ethene undergoes polymerization but not ethane?
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.)
Compound that contains a double or a triple covalent bond?
Ethene, also called ethylene, is the simplest compound with a double covalent bond, and ethyne, also called acetylene, is the simples compound with a triple covalent bond.
What is the best description of the carbon-carbon bonds in ethene C2H4?
Two sp2 orbitals overlap to form a sigma bond, and two 2p orbitals overlap to form a pi bond.
