An alkyne has 8 carbon atoms. The number of hydrogen atoms in it are

Options

A. 8
B. 16
C. 18
D. 14

Explanation

To find the number of hydrogen atoms in an alkyne with 8 carbon atoms, we can follow these steps:

### Step 1: Understand the General Formula for Alkynes
The general formula for alkynes is given by:
\[ C_nH_{2n-2} \]
where \( n \) is the number of carbon atoms.

### Step 2: Identify the Number of Carbon Atoms
In this case, we are given that the alkyne has 8 carbon atoms. Therefore:
\[ n = 8 \]

### Step 3: Substitute the Value of \( n \) into the Formula
Now, we substitute \( n \) into the general formula to find the number of hydrogen atoms:
\[ H = 2n - 2 \]

### Step 4: Calculate the Number of Hydrogen Atoms
Substituting \( n = 8 \):
\[ H = 2(8) - 2 \]
\[ H = 16 - 2 \]
\[ H = 14 \]

### Step 5: Conclusion
Thus, the number of hydrogen atoms in an alkyne with 8 carbon atoms is:
\[ \text{H} = 14 \]

### Final Answer
The number of hydrogen atoms in the alkyne is **14**.
