What is the IUPAC name of the alcohol: `HC-=C-CH_(2)OH`?

Explanation

To determine the IUPAC name of the alcohol `HC≡C-CH₂OH`, we will follow these steps:

### Step 1: Identify the longest carbon chain
The structure has a total of three carbon atoms. The longest chain includes all three carbons, which gives us a propyl chain.

### Step 2: Number the carbon chain
We will number the carbon chain from the end closest to the hydroxyl (–OH) group to give it the lowest possible number. In this case, we will number the carbons as follows:
1. C1: The carbon with the hydroxyl group (–OH)
