### Reaction Scheme of an Alkane Transformation

This diagram illustrates a multi-step transformation of an alkane compound using various reagents.

1. **Starting Material: Alkane**
   - A simple alkane is the starting material for this reaction sequence.

2. **Reagents and Conditions:**
   - **Step 1:** \( \text{Br}_2/\text{light} \) - Bromination of the alkane under photochemical conditions.
   - **Step 2:** \( \text{1 equiv. KOtBu} \) - Dehydrohalogenation using potassium tert-butoxide to form an alkene.
   - **Step 3:** \( \text{BH}_3 \) - Hydroboration of the alkene.
   - **Step 4:** \( \text{H}_2\text{O}_2/\text{NaOH} \) - Oxidative workup to convert the borane intermediate into an alcohol.
   - **Step 5:** \( \text{PCC} \) - Oxidation of the alcohol to form an aldehyde or ketone using pyridinium chlorochromate.

### Diagram Explanation

- **Overall Structure:**
  - The arrows and sequence numbers indicate the progression of the chemical reaction steps.
  - The toolbar at the bottom ("ChemDoodle") suggests the diagram was constructed using a digital chemical drawing tool, but does not add specific educational content.

This transformation demonstrates a sequence of typical organic reactions including halogenation, elimination, hydroboration, oxidation, and potentially further functional group modification.
