`(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, we need to write the IUPAC names of the given compounds and classify them as primary, secondary, or tertiary amines. Let's go through each compound step by step.

### Step 1: Analyze Compound (i) (CH₃)₂CHNH₂
- The structure consists of a carbon chain with two methyl groups (CH₃) and an amine group (NH₂).
- The longest carbon chain is 2 carbons (ethane).
- The IUPAC name is **1-methyl-ethanamine**.
- Classification: This compound has one alkyl group attached to nitrogen, making it a **primary amine**.
