Here are the essential concepts you must grasp in order to answer the question correctly.
Ozonolysis
Ozonolysis is a reaction involving the cleavage of carbon-carbon double bonds (alkenes) using ozone (O3). This reaction typically results in the formation of carbonyl compounds, such as aldehydes or ketones, depending on the structure of the starting alkene. The process involves the formation of a cyclic ozonide intermediate, which is subsequently reduced to yield the final products.

Dimethyl Sulfide (DMS) Reduction
Dimethyl sulfide (DMS) is commonly used as a reducing agent in organic chemistry, particularly in the workup of ozonolysis reactions. After ozonolysis, the ozonide intermediate can be treated with DMS, which reduces the carbonyl compounds formed into their corresponding alcohols or further reduces them to hydrocarbons. This step is crucial for transforming the ozonolysis products into more stable or desired forms.

Hydrocarbon Structure
Understanding the structure of hydrocarbons is essential for predicting the products of reactions like ozonolysis. Hydrocarbons can be aliphatic (straight or branched chains) or aromatic (cyclic structures with delocalized electrons). The specific arrangement of carbon and hydrogen atoms influences how the molecule reacts with ozone and DMS, ultimately determining the nature of the products formed in the reaction sequence.
