Phosgene is the common name for :

Options

A. `CO_(2) and PH_(3)`
B. Phosphoryl chloride
C. Carbonyl chloride
D. Carbon tetrachloride

Answer

To determine the common name for phosgene, we will analyze the options provided in the question step by step.

### Step 1: Understand the definition of phosgene
Phosgene is known to be a toxic compound that is used in the production of pharmaceuticals and pesticides. It is important to identify its chemical structure and formula.

**Hint:** Look for the chemical formula associated with phosgene in your chemistry notes.

### Step 2: Analyze the options given
We have four options to consider:
- Option A: CO2 and PH3
- Option B: Phosphoride fluoride
- Option C: Carbonyl chloride
- Option D: Carbon tetrachloride

**Hint:** Recall the chemical formulas and common names of the compounds listed in the options.

### Step 3: Evaluate each option
- **Option A (CO2 and PH3)**: CO2 is carbon dioxide, which is not phosgene. PH3 is phosphine, which is also not related to phosgene.

- **Option B (Phosphoride fluoride)**: This does not correspond to phosgene and is not a commonly known compound.

- **Option C (Carbonyl chloride)**: This is the correct chemical name for phosgene. The chemical formula for phosgene is COCl2, which is indeed carbonyl chloride.

- **Option D (Carbon tetrachloride)**: This is a different compound (CCl4) and is not phosgene.

**Hint:** Focus on the chemical formula COCl2 to identify the correct name.

### Step 4: Conclusion
Based on the analysis, the common name for phosgene is **Carbonyl chloride** (Option C).

**Final Answer:** Phosgene is the common name for **Carbonyl chloride** (Option C).
