Fill in the missing products for when the following molecule is reacted with the reagent.

The image depicts a chemical reaction involving an organic compound undergoing ozonolysis. The compound is a polyhydroxylated chain, likely a sugar alcohol, featuring multiple hydroxyl (OH) groups along its carbon backbone.

**Reaction Details:**

1. **Reactant Structure:**
   - The molecule includes a series of carbon atoms with hydroxyl groups (OH) attached, indicating the presence of multiple alcohol functional groups.

2. **Reaction Conditions:**
   - Step 1: Ozonolysis is initiated using ozone (O₃), which cleaves the carbon-carbon double bonds (if any) in the compound.
   - Step 2: Methyldisulfide (Me₂S) is used as a reductive work-up agent. This reduces the ozonide intermediates to form aldehydes or ketones without further oxidation to carboxylic acids.

**Concept Explanation:**

Ozonolysis is a chemical reaction where ozone acts on alkenes or polyhydroxylated compounds to cleave double bonds, resulting in the formation of smaller aldehyde or ketone compounds. The use of Me₂S specifically helps maintain the reduced form of ozonolysis products, preventing complete oxidation. This reaction is significant in organic synthesis for its ability to facilitate the study and manipulation of complex molecules by selectively breaking down carbon chains.
