**Exercise 2: Predict the Products**

In the following reactions, identify the products formed.

**a) Reaction with PCC**

- **Reactant:** Cyclohexanol (cyclohexane with an OH group)
- **Reagent:** PCC (Pyridinium chlorochromate)
- **Product:** The reaction involves the oxidation of the alcohol group to form a ketone.

**b) Reaction with NaBH₄**

- **Reactant:** A ketone with the structure CH₃CH₂C(O)CH₂CH₃ (a five-carbon chain with a carbonyl group)
- **Reagent:** NaBH₄ (Sodium borohydride)
- **Product:** The ketone is reduced to an alcohol, specifically a secondary alcohol.

**c) Hydroboration-Oxidation Reaction**

- **Reactant:** An alkene (shown as a simple linear structural formula)
- **Reagents:** 
  1. BH₃ (Borane)
  2. H₂O₂, OH⁻ (Hydrogen peroxide and hydroxide)
- **Product:** The alkene undergoes hydroboration-oxidation to form an alcohol, typically following anti-Markovnikov addition.

Each step should help you understand the transformation of functional groups during the reactions, highlighting the ability to predict outcomes based on typical organic chemistry mechanisms.
