Answer

To convert alkyl halides into alcohols, the process involves a substitution reaction. Here’s a step-by-step explanation:

### Step 1: Identify the Reactants
- The reactants in this process are alkyl halides (RX) and a hydroxide source, typically aqueous potassium hydroxide (KOH).

### Step 2: Understand the Mechanism
- In the substitution reaction, the halide (X) in the alkyl halide is replaced by a hydroxyl group (OH). This means that the halide ion leaves, and the hydroxyl group takes its place.

### Step 3: Reaction Process
- When the alkyl halide (RX) is treated with aqueous KOH, the hydroxide ion (OH⁻) acts as a nucleophile. It attacks the carbon atom bonded to the halide (X), leading to the formation of an alcohol (ROH).

### Step 4: Formation of Products
- The reaction can be summarized as follows:
\[ RX + KOH \rightarrow ROH + KX \]
- Here, ROH is the alcohol formed, and KX is the by-product, which is a potassium halide.

### Step 5: Conclusion
- The process of converting alkyl halides into alcohols is thus classified as a substitution reaction, specifically an S_N2 mechanism for primary and some secondary alkyl halides, where the nucleophile attacks the carbon atom from the opposite side of the leaving group.

### Final Answer
- The process of converting alkyl halides into alcohols involves a **substitution reaction**.
