(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 problem step by step, we will identify the isomeric amines corresponding to the molecular formula \( C_4H_{11}N \), write their structures, provide their IUPAC names, and determine the types of isomerism exhibited by the different pairs of amines.

### Step 1: Identify Isomeric Amines
We will start by identifying the possible isomers of amines with the molecular formula \( C_4H_{11}N \). Amines can be classified as primary, secondary, or tertiary based on the number of carbon atoms attached to the nitrogen atom.
