Draw the electron dot structure of ethyne. A mixture of ethyne and onygen is burnt for welding In your opinion, why camalot we use a mixture of ethyne and air for this purpose.

Explanation

Electron dot structure of ethyne -

No, the mixture of ethyne and air cannot be used for welding because when ethyne is burnt is 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.
