Options

A. `K_(2)Cr_(2) O_(7)`
B. `CrO_(3)`
C. `KMnO_(4)`
D. `PC C `

Answer

To convert a primary alcohol (RCH₂OH) to an aldehyde (RCHO), we need to choose the appropriate oxidizing agent. Here’s a step-by-step solution to the question:

### Step 1: Identify the Type of Alcohol
- The compound RCH₂OH is a primary alcohol. Primary alcohols have the hydroxyl (-OH) group attached to a carbon that is bonded to only one other carbon atom.

**Hint:** Recognize the structure of primary alcohols and their reactivity.

### Step 2: Understand Oxidation Reactions
- Primary alcohols can be oxidized to aldehydes. However, strong oxidizing agents can further oxidize aldehydes to carboxylic acids.

**Hint:** Remember that the strength of the oxidizing agent affects the final product of the reaction.

### Step 3: Evaluate the Given Reagents
- **K₂Cr₂O₇ (Potassium dichromate)**: A strong oxidizing agent that can oxidize primary alcohols to carboxylic acids.
- **CrO₃ (Chromium trioxide)**: Another strong oxidizing agent that will also convert primary alcohols to carboxylic acids.
- **KMnO₄ (Potassium permanganate)**: A strong oxidizing agent that can oxidize primary alcohols to carboxylic acids as well.
- **PCC (Pyridinium chlorochromate)**: A mild oxidizing agent that selectively oxidizes primary alcohols to aldehydes without further oxidation to carboxylic acids.

**Hint:** Compare the reactivity of each reagent with the desired product.

### Step 4: Choose the Most Suitable Reagent
- Since we want to convert RCH₂OH to RCHO (aldehyde) without further oxidation to a carboxylic acid, the most suitable reagent is PCC. It is specifically designed to oxidize primary alcohols to aldehydes.

**Hint:** Focus on the desired outcome of the reaction when selecting the reagent.

### Conclusion
- The most suitable reagent for the conversion of RCH₂OH to RCHO is **PCC (Pyridinium chlorochromate)**.

**Final Answer:** **PCC (Option D)**
