The carbon atom doesn't have enough unpaired electrons to form four bonds (1 to the hydrogen and three to the other carbon), so it needs to promote one of the 2s 2 pair into the empty 2p z orbital.

For the C2H2 structure use the periodic table to find the total number of valence electrons for the C2H2 molecule. The electron dot structure of Ethyne is as follow : 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.
