Write down the bond line structure of the following:
1-hexyne

Explanation

To draw the bond line structure of 1-hexyne, follow these steps:

### Step 1: Identify the number of carbon atoms
1-hexyne indicates that there are 6 carbon atoms in the chain (the prefix "hex" refers to six).

### Step 2: Determine the type of bond
The suffix "yne" indicates that there is a triple bond present in the molecule. Since it is 1-hexyne, the triple bond is located between the first and second carbon atoms.
