Which of the following alkenes forms formaldehyde and acetaldehyde on ozonolysis?

Step-by-step solution

Ozonolysis of an alkene involves the cleavage of the carbon-carbon double bond to form carbonyl compounds. To find the original alkene, we remove the oxygen atoms from the carbonyl products and join the carbon atoms with a double bond. The given products are formaldehyde ( HCHO ) and acetaldehyde ( CH₃CHO ). Joining the carbonyl carbons of HCHO and CH₃CHO gives CH₃-CH=CH₂ , which is propene. Reaction: CH₃-CH=CH₂ O₃, Zn/H₂O CH₃CHO + HCHO Thus, propene forms formaldehyde and acetaldehyde on ozonolysis. Answer: Propen
