IUPAC name of `CH_(3)(CH_(2))_(2)NH_(2)` is

Options

A. 1-Propanamine
B. 2-Methyl ethanamine
C. Iso-Propylamine
D. `2^(@)`-Propylamine

Explanation

To find the IUPAC name of the compound `CH₃(CH₂)₂NH₂`, we can follow these steps:

### Step 1: Identify the Structure
The given molecular formula can be expanded to show the structure:
- `CH₃` is a methyl group.
- `CH₂` is a methylene group, and there are two of them.
- `NH₂` is an amino group.

The complete structure can be represented as:
```
CH3
|
CH2-CH2-NH2
```

### Step 2: Determine the Longest Carbon Chain
Next, we need to identify the longest continuous carbon chain in the structure. In this case, the longest chain consists of three carbon atoms:
```
CH3
|
CH2-CH2
```
This gives us a straight-chain alkane with three carbon atoms.

### Step 3: Name the Carbon Chain
The name of a straight-chain alkane with three carbon atoms is "propane".

### Step 4: Identify the Functional Group
The functional group present in this compound is the amine group (`-NH₂`). Since the amino group is attached to the first carbon of the longest chain, we classify this as a primary amine.

### Step 5: Combine the Names
To combine the names, we use the name of the longest carbon chain followed by the name of the functional group. Since the amino group is on the first carbon, we prefix "1-" to the name of the amine.

Thus, the IUPAC name becomes:
**1-propanamine**

### Final Answer
The IUPAC name of `CH₃(CH₂)₂NH₂` is **1-propanamine**.
