C. If assertion is true but reason is false .
D. if both assertion and reason are false.

Answer

To solve the question, we need to analyze the assertion and the reason provided.

**Assertion:** Alcohols react both as nucleophiles and electrophiles.

**Reason:** Alcohols react with active metals such as sodium, potassium, and aluminum to yield corresponding alkoxides and hydrogen.

### Step-by-Step Solution:

1. **Understanding Nucleophilicity of Alcohols:**
- Alcohols can act as nucleophiles due to the presence of a lone pair of electrons on the oxygen atom. This lone pair can attack electrophilic centers in other molecules.
- Example: When an alcohol (R-OH) reacts with an alkyl halide (R'-X), the oxygen's lone pair attacks the carbon atom bonded to the halogen, leading to the formation of an ether (ROR') and the halogen leaving as a halide ion (X^-).

2. **Understanding Electrophilicity of Alcohols:**
- Alcohols can also act as electrophiles when the C-O bond breaks. In this case, the alcohol can react with strong acids (like HBr).
- Example: In the presence of HBr, the alcohol (R-OH) can form a carbocation (R^+) after the C-O bond breaks and the oxygen atom protonates. This carbocation can then react with a nucleophile (like Br^-) to form an alkyl halide (R-Br).

3. **Analyzing the Reason:**
- The reason states that alcohols react with active metals (like sodium, potassium, and aluminum) to form alkoxides (R-O-M, where M is the metal) and hydrogen gas (H2).
- This reaction is indeed correct. For example, when sodium reacts with methanol (CH3OH), it forms sodium methoxide (CH3ONa) and hydrogen gas (H2).

4. **Conclusion:**
- Both the assertion and the reason are true statements.
- However, the reason does not directly explain why alcohols can act as both nucleophiles and electrophiles. The reason discusses a specific reaction of alcohols with metals rather than the general behavior of alcohols as nucleophiles and electrophiles.

### Final Answer:
The correct option is: **Option 2** - Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
