Question

Draw the structure of the starting material in the ozonolysis reaction below. Hint: The starting material and product have the same number of carbons (i.e., 1 mol reactant : 1 mol product).

Answer 1

Answer:

            The starting material involved in the formation of 5-Oxoheptanal is 1-ethylcyclopent-1-ene as shown in reaction below.

Explanation:

                       Ozone is one of the reactive allotrope of oxygen. It reacts vigorously with unsaturated compounds like alkenes and alkynes. In this reaction alkene and O₃ first react to produce Molozonide which is highly unstable and rearranges to form a stable ozonide as shown in scheme attached below.

                      Furthermore, the ozonide on reduction is convertwed into ketones and aldehydes respectively.

Answer 2

Please see attached picture for the starting material in the ozonolysis reaction given. Ozonolysis is an organic reaction that allows the cleavage or splittling of the alkene double bonds by reaction with ozone. Hope this helps.
