Answer 2

Hello Students,

# Electron dot structure of ethyne -

[Refer to the image attachment for electron dot structure of ethyne.]

# Mixture of ethyne and air can't be used for welding because -

• Ethyne when burnt with oxygen gives clean flame due to complete combustion. Hence, ethylene + oxygen is used for welding.
• On the other hand, ethyne when burnt with air gives sooty flame due to incomplete combustion. Hence, ethylene + air is not suitable for welding.
