Write structures of different isomers corresponding to the 5th member of alkyne series. Also write IUPAC names of all the isomers. What type of isomerism is exhibited by different pairs of isomers?

Explanation

To solve the problem of finding the structures and IUPAC names of different isomers corresponding to the 5th member of the alkyne series, we will follow these steps:

### Step 1: Identify the 5th member of the alkyne series
The general formula for alkynes is CnH2n-2. For n = 6, the molecular formula is C6H10.

### Step 2: Determine the possible structures (isomers)
We will explore the different structural isomers of C6H10, which include positional isomers and chain isomers.
