Which compound to use for treatment of tumor?

Options

A. `Cis[PdCl_(2)(NH_(3))_(2)]`
B. Trans `[PdCl_(2)(NH_(3))_(2)]`
C. `Cis[PtCl_(2)(NH_(3))_(2)]`
D. Trans `[PtCl_(2)(NH_(3))_(2)]`

Answer

To determine which compound is used for the treatment of tumors, we will analyze the given options step by step.

### Step 1: Identify the Compounds
We have four options to consider:
1. **Cis-Pd(Cl)₂(NH₃)₂**
2. **Trans-Pd(Cl)₂(NH₃)₂**
3. **Cis-Pt(Cl)₂(NH₃)₂**
4. **Trans-Pt(Cl)₂(NH₃)₂**

### Step 2: Eliminate Incorrect Options
We need to identify which of these compounds is used for tumor treatment. Tumors are a type of cancer, and certain compounds are known as chemotherapeutic agents.

- **Palladium (Pd)** is not typically used for cancer treatment. Therefore, we can eliminate options 1 and 2 (Cis and Trans Palladium compounds).

### Step 3: Focus on Platinum Compounds
Now we are left with:
3. **Cis-Pt(Cl)₂(NH₃)₂**
4. **Trans-Pt(Cl)₂(NH₃)₂**

### Step 4: Identify the Correct Isomer
Among the platinum compounds, the one that is widely recognized for its effectiveness in treating tumors, particularly testicular and ovarian cancers, is **Cisplatin**. The IUPAC name for this compound is **cis-diamminedichloroplatinum(II)**.

- **Cisplatin** has the following structure:
- Platinum (Pt) is at the center, with two ammonia (NH₃) ligands and two chloride (Cl) ligands arranged in a cis configuration.

### Step 5: Conclusion
Thus, the compound used for the treatment of tumors is **Cis-Pt(Cl)₂(NH₃)₂**, which corresponds to option 3.

### Final Answer:
**Option 3: Cis-Pt(Cl)₂(NH₃)₂ is the correct answer.**
