Write IUPAC names of the following compounds and classify them into primary, secondary and tertiary amines.
`(i)(CH_(3))_(2)CHNH_(2)" "(ii)CH_(3)(CH_(2))_(2)NH_(2)" "(iii)CH_(3)NHCH(CH_(3))_(2)`
`(iv)(CH_(3))_(3)CNH_(2)" "(v)C_(6)H_(5)NHCH_(3)" "(vi)(CH_(3)CH_(2))_(2)NCH_(3)`
`(vii) m-BrC_(6)H_(4)NH_(2)`

Explanation

To solve the problem of naming the given amines and classifying them as primary, secondary, or tertiary, we will follow these steps:

### Step 1: Identify the structure of each compound and classify them.

1. **Compound (i): (CH₃)₂CHNH₂**
- Structure: This compound has two methyl groups (CH₃) and one ethyl group (CH) attached to the nitrogen (NH₂).
- Classification: The nitrogen is connected to one alkyl chain and has two hydrogen atoms, making it a **primary amine**.
- IUPAC Name: **Propan-1-amine** (or **isopropylamine**).
