How many diffrent carbonyl compounds are formed on reductive ozonolysisof o-xylene?

Question

please can u helpme with this question>?

Answer 1

The reductive ozonolysis of alkenes cleaves those alkenes and leaves two carbonyl functional groups in place of both alkene carbons. Ortho xylene is a benzene derivative which, as you know, may behave very differently from simple or even conjugated alkenes, BUT ozone is a powerful oxidant, and under the right conditions will react with benzene and its derivatives.

You must look at both Kekule forms of o-xylene. Then, cleaving each "double bond" to leave either a ketone or aldehyde carbonyl, you predict that THREE different carbonyl compounds will be formed.
