Write the systematic IUPAC names of the following compounds :
`CH_3 - underset(C_2 H_5 ) underset(|) overset(CH_3) overset(|) C- CH_2 - overset(C_2 H_5 ) overset(|) CH-NH_2`

Explanation

To determine the systematic IUPAC name of the given compound, we will follow these steps:

### Step 1: Identify the longest carbon chain
First, we need to identify the longest continuous carbon chain in the compound. The structure provided indicates that there are 7 carbon atoms in the longest chain.

### Step 2: Number the carbon chain
Next, 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 that is closest to the amine group (-NH2).
