By combustion ethyne is transformed in carbon dioxide and water.
The balanced equation for the complete combustion of ethyne (C2H2) is: 2C2H2 + 5O2 -> 4CO2 + 2H2O
It is the balanced equation for the combustion of acetylene (or ethyne).
The properly balanced combustion reaction is given by (don't care about N2 on the product side) C2H2 + 5/2 (O2 + 3.75N2) -> 2CO2 + H2O + N2 So, the molar air to fuel ratio for complete combustion is 2/5.
colourless
violet or purple colour
Oxygen is much more dense than ethyne. This is why a test tube full of ethyne would be held upside down so the ethyne doesnt escape into the air.
polar
The chemical formula of ethyne (acerylene) is C2H2 - two hydrogen atoms.
ethyne (or acetylene) is non polar
Yes, ethyne (acetylene) can react with bromine to form 1,2-dibromoethane. This is an addition reaction where the bromine atoms add across the carbon-carbon triple bond in ethyne.
When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean flame with temperature 3000°C because of complete combustion. This oxy-acetylene flame is used for welding. It is not possible to attain such a high temperature without mixing oxygen. This is the reason why a mixture of ethyne and air is not used. Hope its fine with u !! all the best !!
Acetylene (C2H2) is also known as ethyne. It is the simplest alkyne.
