Ozonolysis of an alkene gave two molecules of ethanal (acetaldehyde). Give the structure of the alkene.

Text Solution

Verified by Experts

[Write the structures of the products with carbobtl groups facing each other. Then remove oxygen atoms from each of the carbonyl compound and put double bonds between the two carbon atoms to get the alkene.]
Products of ozonolysis :`CH_3-CHO`(ethanol) `OHC-CH_3` (ethanal)
Hence the structure of alkene is `CH_3-CH=CH-CH_3`(but-2-ene)
