IUPAC name of-
`CH_(3)-underset(NH_(2))underset(|)CH-CH_(3)` is-

Options

A. Dimethyl amine
B. 2-aminopropane
C. Isopropylamine
D. 2-propanamine

Explanation

To determine the IUPAC name of the compound `CH₃-NH₂ | CH-CH₃`, we will follow these steps:

### Step 1: Identify the Longest Carbon Chain
The first step in naming an organic compound is to identify the longest continuous carbon chain. In this case, we have a chain of three carbon atoms.

### Step 2: Identify the Functional Group
Next, we need to identify the functional groups present in the compound. Here, we have an amino group (-NH₂) attached to the carbon chain.

### Step 3: Number the Carbon Chain
We will number the carbon chain starting from the end closest to the functional group. In this case, we will start numbering from the end where the amino group is attached:
1. C1 - NH₂
2. C2 - CH
3. C3 - CH₃

### Step 4: Determine the Substituents and Their Positions
The amino group is located at carbon 2. Therefore, we will use the prefix "amino" to indicate the presence of the amino group.

### Step 5: Combine the Information
Now we can combine the information:
- The parent chain is propane (since it has three carbon atoms).
- The amino group is on carbon 2.

Thus, the IUPAC name of the compound is **2-amino propane**.

### Final Answer
The IUPAC name of the compound `CH₃-NH₂ | CH-CH₃` is **2-amino propane**.
