Write IUPAC name of `CH_(3)-CH_(2)-NH_(2)`

Explanation

To determine the IUPAC name of the compound `CH₃-CH₂-NH₂`, we can follow these steps:

### Step 1: Identify the longest carbon chain
The compound has a two-carbon chain, which can be identified as follows:
- The first carbon (C1) is attached to three hydrogen atoms (CH₃).
- The second carbon (C2) is attached to two hydrogen atoms and one nitrogen atom (NH₂).

### Step 2: Name the carbon chain
Since there are two carbon atoms in the longest chain, the base name will be derived from "ethane," which corresponds to two carbon atoms.

### Step 3: Identify the functional group
The functional group present in this compound is the amine group (NH₂). In IUPAC nomenclature, amines are named by adding "amine" to the base name of the carbon chain.

### Step 4: Combine the names
Since we have a two-carbon chain (ethane) with an amine group, we combine these to form the IUPAC name:
- The name becomes "ethanamine."

### Final Answer
The IUPAC name of the compound `CH₃-CH₂-NH₂` is **ethanamine**.
