Options

A. `C_6H_12+H_2`
B. `C_4H_3+C_2H_6`
C. `C_3H_6+C_2H_4+CH_4`
D. All of the above

Answer

To determine the possible products when hexane (C6H14) is heated at a temperature of 773 K, we can analyze the process of pyrolysis, which involves the thermal decomposition of hydrocarbons.

### Step-by-Step Solution:

1. **Identify the Compound**:
- The compound in question is hexane, which has the molecular formula C6H14.

2. **Understand the Process**:
- When hexane is heated to high temperatures (like 773 K), it undergoes pyrolysis. Pyrolysis is a process where larger hydrocarbons break down into smaller hydrocarbons and other products.

3. **Decomposition of Hexane**:
- The pyrolysis of hexane can lead to the formation of various smaller hydrocarbons. The general reaction can be represented as:
\[ C_6H_{14} \rightarrow C_nH_m + \text{other products} \]
- Here, \( C_nH_m \) represents the smaller hydrocarbons formed.

4. **Possible Products**:
- From the pyrolysis of hexane, we can obtain:
- **C6H12** (hexene) + H2
- **C4H8** (butene) + **C2H6** (ethane)
- **C3H6** (propene) + **C2H4** (ethylene) + **CH4** (methane)

5. **Summarize the Products**:
- The possible products from the pyrolysis of hexane at 773 K include:
- Hexene (C6H12)
- Butene (C4H8)
- Ethane (C2H6)
- Propene (C3H6)
- Ethylene (C2H4)
- Methane (CH4)

6. **Conclusion**:
- Therefore, the possible products when hexane is heated at 773 K are a mixture of lower hydrocarbons including ethane, propane, butane, and others.
