Here are the essential concepts you must grasp in order to answer the question correctly.
Catalytic Hydrogenation
Catalytic hydrogenation is a chemical reaction that involves the addition of hydrogen (H2) to unsaturated organic compounds, typically in the presence of a catalyst such as palladium, platinum, or nickel. This process converts alkenes or alkynes into alkanes, effectively saturating the molecule. Understanding this concept is crucial for deducing the structure of compounds Y and Z, as it provides insight into how these compounds can be transformed into simpler saturated forms.

Ozonolysis
Ozonolysis is a reaction involving the cleavage of alkenes or alkynes using ozone (O3), resulting in the formation of carbonyl compounds, such as aldehydes or ketones. This reaction is significant in organic synthesis for determining the structure of complex molecules, as it breaks down larger structures into identifiable fragments. In the context of the question, ozonolysis helps to identify the components of compounds Y and Z after their hydrogenation.

Bicyclic Compounds
Bicyclic compounds are organic molecules that contain two interconnected rings. Their unique structure can influence their reactivity and stability, making them important in organic chemistry. In the case of compound Z, the formation of cis-bicyclo[4.2.0]octane upon hydrogenation indicates specific stereochemical and structural features that must be considered when deducing its original structure. Understanding bicyclic systems is essential for accurately interpreting the results of the reactions described.
