A saturated hydrocarbon has the formula `C_(n)H_(12)`. The value of 'n' in this compound is

Options

A. 4
B. 5
C. 6
D. 2

Answer

To find the value of 'n' in the saturated hydrocarbon with the formula \( C_nH_{12} \), we can use the general formula for saturated hydrocarbons, which is \( C_nH_{2n+2} \).

### Step-by-step Solution:

1. **Identify the General Formula**:
The general formula for saturated hydrocarbons (alkanes) is given by:
\[ C_nH_{2n+2} \]

2. **Set Up the Equation**:
We know from the question that the hydrocarbon has the formula \( C_nH_{12} \). Therefore, we can set up the equation:
\[ 2n + 2 = 12 \]

3. **Solve for 'n'**:
To find 'n', we will solve the equation:
\[ 2n + 2 = 12 \]
Subtract 2 from both sides:
\[ 2n = 10 \]
Now, divide both sides by 2:
\[ n = 5 \]

4. **Conclusion**:
The value of 'n' in the compound \( C_nH_{12} \) is:
\[ n = 5 \]

### Final Answer:
The value of 'n' is 5.
