What are the products obtained from the following reaction? `CHCL_3 + O_2 --rarr(^light)`

Options

A. HCHO and HCI
B. HCOCI and HCI
C. `COCI_2` and HCI
D. `COCI_2` and HCOCI

Answer

To determine the products obtained from the reaction of chloroform (CHCl₃) with oxygen (O₂) in the presence of light, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Chloroform (CHCl₃)
- Oxygen (O₂)

### Step 2: Understand the Reaction Conditions
The reaction occurs in the presence of light, which indicates that it is a photochemical reaction. This type of reaction often leads to the breaking of bonds and the formation of new products.

### Step 3: Determine the Products
When chloroform reacts with half a molecule of oxygen (O₂) under light, the products formed are:
- Carbonyl chloride (COCl₂)
- Hydrogen chloride (HCl)

### Step 4: Write the Balanced Reaction
The balanced chemical equation for the reaction can be represented as:
\[ \text{CHCl}_3 + \frac{1}{2} \text{O}_2 \xrightarrow{\text{light}} \text{COCl}_2 + \text{HCl} \]

### Step 5: Identify the Nature of the Products
- **Carbonyl chloride (COCl₂)**, commonly known as phosgene, is a highly toxic gas with a smell reminiscent of freshly cut grass.
- **Hydrogen chloride (HCl)** is a gas that can dissolve in water to form hydrochloric acid.

### Conclusion
The products obtained from the reaction of chloroform with oxygen in the presence of light are carbonyl chloride (COCl₂) and hydrogen chloride (HCl).
