Propanal and pentan-3-one are the ozonolysis products of an alkene? What is the structural formula of the alkene?

Explanation

The products of the ozonolysis are, `underset("Propanal")(CH_(3)-CH_(2)-underset(underset(H)(|))(C )= O) and O= underset("Pentan-3-one")(underset(underset((CH_(2)-CH_(3)))(|))(C )- CH_(2)- CH_(3))`
The structural formula of the parent alkene is obtained by removing the O atoms of the two products and joining the two products by a double bond. Therefore, we get the following structure of parent alkene:
`underset("3-ethylhex-3-ene")(overset(6)(C )H_(3)- overset(5)(C )H_(2)- underset(underset(H)(|))overset(4)(C )= underset(underset(CH_(2)-CH_(3))(|))overset(3)(C )- overset(2)(C )H_(2)- overset(1)(C)H_(3))`
