acetylene first forms an ozonide intermediate with ozone
 
after wards it(intermediate) gets decomposed by water to form glyoxal and hydrogen peroxide
 
glyoxal and hydrogen peroxide react to form  formic acid
FINAL PRODUCT IS FORMIC ACID
 
hope u got it.......
plzzzz rate me

Acetylene reacts with ozone to give an ozonide which on decomposition with water yields glyoxal.

Yes first an molozonide is formed then an ozonide is formed then we have aldehydes for reductive ozonolysis and formic acid for oxidative ozonolysis!!!
