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.
Can anyone give me some examples of a substance whose molecules contain pi-bonds?
Ethene and ethyne.
How can you convert ethene into glycol?
Athene + steam = ethanol (this process is call hydrogenation) C2H4 + H2O = C2H5OH as it is a reversible reaction so if you carry out dehydration process of Ethanol you will have Athene Ethanol = Athene + Water
Is ethyne a unsaturated hyrocarbon?
Yes, any hydrocarbon with C & H with a double or triple bond is unsaturated
What are the 3 basic shapes of carbon molecules?
The three basic shapes of carbon molecules are linear (such as in ethyne), trigonal planar (such as in ethene), and tetrahedral (such as in methane). These shapes are determined by the number of bonding pairs and lone pairs around the carbon atom.
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 is the name of the smallest alkene?
The smallest alkyne is ethyne (C2H2). You're welcome!
What are examples of hydrocarbons?
Examples of hydrocarbons include methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), and hexane (C6H14). These compounds consist of carbon and hydrogen atoms bonded together and can be found in natural gas, gasoline, and other fossil fuels.
Why is ethene the smallest unsaturated hydrocarbon molecule?
Ethene has the simplest unsaturated hydrocarbon structure because it consists of two carbon atoms connected by a double bond and carrying two hydrogen atoms each. This simple structure makes it the smallest unsaturated hydrocarbon molecule.
How can you distinguish between ethene and ethyne by means of a chemical reaction?
One way to distinguish between ethene and ethyne is by performing a bromine water test. Ethene will decolorize bromine water, turning it from orange to colorless, while ethyne will not react with bromine water. This test takes advantage of the unsaturation in ethene that allows it to quickly react with bromine.
How ethyne is converted into ethane?
Ethyne (C2H2) can be converted into ethane (C2H6) by addition of hydrogen gas (H2) in the presence of a suitable catalyst, such as palladium or platinum. This process is known as hydrogenation and involves breaking the triple bond in ethyne and adding hydrogen atoms to form single bonds between carbon atoms in ethane.
What is the compound name for c2?
What is 'c2' ; Never heard of it. However, if you mean H3C-CH3 ( ethane) H2C=CH2 ) ethene) HC///CH (ethyne) Note the different spellings for each molecule.
Which is a hydrocarbon?
They can be any one of the three under normal conditions, it depends on the molecular weight. Lighter ones such as methane, ethane ethene, ethyne are gases. Pentane hexane and heavier up to around C19 are liquids. High molecular weight hydrocarbons above say C20H42 are waxes.
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.

The ability to form into long chains is due to the double bond between the carbon atoms in the ethene molecule.
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.)
Example of alkane?
AlkAnes are any hydrocarbons that have single C-C covalent bonds . e.g. Ethane, or propane to name but two. Structurally ethane is H3C-CH3 Do Not confuse with AlkEnes and AlkYnes Alkenes are hydrocarbons that have at least one pair of carbons with a double (C=C) covalent bond between them. e.g. Ethene , Propene to name but two . Structurally, ethene is H2C=CH2 Alkynes are hydrocarbons that have at least one pair of carbons with a triple (C///C)covalent bond between them. e.g. Ethyne(acetylene), Butyne. to name but two. Structurally ethyne is HC///CH Note the reduction in hydrogens for each additional covalent bond. Be careful when writing the names. There is only ONE letter difference between functional groups. viz. 'a', 'e' or 'y'.
