Draw the electron-dot structure for ethyne. A mixture of ethyne and oxygen is burnt for welding. In your opinion, why cannot we use a mixture of ethyne and air for this purpose?
The electron dot structure of Ethyne is as follows:
We can’t use a mixture of ethyne and air for the welding purpose because air has less amount of Oxygen present in it than that of pure Oxygen, due to which incomplete combustion occurs and the temperature which is needed for welding air not attained. Therefore Pure Oxygen is used as it supports complete combustion.
