Ozonolysis of acetylene gives:
Correct answer: B. Glyoxal then formic acid
- A. Glycol
- B. Glyoxal then formic acid
- C. Formaldehyde
- D. None
Explanation
Ozonolysis of acetylene first forms glyoxal, OHC-CHO, and further oxidation converts the aldehyde groups to formic acid. Thus the sequence is glyoxal followed by formic acid. The likely mistake is choosing formaldehyde, which is associated with cleavage of ethene, not the oxidative cleavage of acetylene.

About Alkynes
Alkynes are unsaturated hydrocarbons containing a carbon-carbon triple bond, with sp-hybridised carbon atoms and a linear arrangement around the bond. The content includes nomenclature, preparation, acidity of terminal alkynes, and addition reactions with hydrogen, halogens, hydrogen halides and water, as well as oxidation.
