(i) Write structures of different isomeric amines corresponding to the molecular formula, `C_(4)H_(11)N.`
ii) Write IUPAC names of all the isomers.
(iii) What type of isomerism is exhibited by different pairs of amines?

Explanation

To solve the question regarding isomeric amines corresponding to the molecular formula C₄H₁₁N, we will break it down into three parts as specified.

### Part (i): Structures of Different Isomeric Amines

1. **Butan-1-amine** (Primary Amine)
- Structure: CH₃-CH₂-CH₂-CH₂-NH₂
- This is a straight-chain amine with the amine group at the end of the chain.
