What is the difference between ethane and ethene

How is vsepr used to classify molecules? What are the units used for the ideal gas law? How does Charle's law relate to breathing? What is the ideal gas law constant? How do you calculate the ideal gas law constant? How do you find density in the ideal gas law? Does ideal gas law apply to liquids? Predict the structure of the product formed. With hydrogen. Alkenes undergo addition reactions with hydrogen, in the presence of a nickel catalyst , to form alkanes.

Notice that:. An orange-brown solution of bromine dissolved in water, called bromine water, is used to distinguish between alkanes and alkenes:. Alkanes and alkenes have different functional groups, so: both undergo complete combustion , but only alkenes can undergo addition reactions Complete combustion The complete combustion of alkanes and alkenes involves the oxidation of hydrocarbons.

This makes the whole molecule a planar molecule. Since there is a double bond, ethene is an unsaturated molecule. The double bond present in this molecule causes the reactivity of this compound. In addition, ethene is used as a monomer for the production of polymers such as polyethylene via addition polymerization. Apart from that, ethene is a plant hormone which can regulate the fruit ripening.

Ethyne is an organic compound having the chemical formula C 2 H 2. The common name of this compound is acetylene. It has a triple bond between the two carbon atoms: one sigma bond and two pi bonds. Therefore there are no un-hybridized p orbitals in those carbon atoms. Each carbon atom has one hydrogen atom bonded via a single bond. The geometry of the molecule is linear, and the structure is planar.

Earlier, ethyne was mainly produced via partial combustion of methane. The simplest process of producing ethyne is through the reaction between calcium carbide and water. The products of this reaction are ethyne gas and calcium carbonate. But, this is difficult in industrial applications because this requires high temperatures.

Therefore, we use the following techniques in the industrial-scale production of ethyne:. Ethane, ethene, and ethyne are small hydrocarbon compounds. Therefore, these compounds are made of only hydrogen and carbon atoms.
