Aldehydes And Ketones

Aldehydes are more easily oxidised than ketones because they have a hydrogen attached to the carbonyl group, which is removed during the oxidation process.

The reaction sequence involves the ozonolysis of the alkene.
The reaction with ozone ( ) splits the alkene to form two carbonyl compounds.
The subsequent reaction with water reduces the intermediate product, leading to the formation of an aldehyde (CH CHO).

Thus, the correct answer is (c).
