Answer

To answer the question about the reactants involved in the Mandeus reaction, we can break down the information provided in the video transcript into a step-by-step solution.

### Step-by-Step Solution:

1. **Identify the Reaction**: The Mandeus reaction is a chemical reaction that involves the reduction of nitriles to primary amines.

2. **List the Reactants**: According to the video, the reactants involved in the Mandeus reaction include:
- Sodium (Na) or Lithium-Aluminium Hydride (LiAlH4)
- Ethanol (C2H5OH) as a solvent
- A nitrile (which is typically a cyanide compound, R-CN)

3. **Understand the Role of Each Reactant**:
- **Sodium or Lithium-Aluminium Hydride**: These are reducing agents that facilitate the reduction of the nitrile to a primary amine.
- **Ethanol**: This acts as a solvent in the reaction, providing a medium for the reactants to interact.
- **Nitrile**: The starting material that is being converted into a primary amine.

4. **Final Product**: The end product of the Mandeus reaction is a primary amine (R-CH2-NH2) derived from the nitrile.

### Conclusion:
The reactants involved in the Mandeus reaction are sodium (or lithium-aluminium hydride), ethanol, and a nitrile compound.
