Write the structures of isomeric hexynes and also give their IUPAC names.

Explanation

To find the isomeric hexynes and their IUPAC names, we will follow these steps:

### Step 1: Understand the structure of hexynes
Hexyne refers to a hydrocarbon with six carbon atoms and at least one triple bond (C≡C). The general formula for hexynes is C₆H₁₀.

### Step 2: Identify the possible positions for the triple bond
The triple bond can be located in different positions along the carbon chain. The possible positions for the triple bond in hexynes are:
- 1st position (Hex-1-yne)
