The `IUPAC` name of the following is `:`
`CH_(3)CH=CH-CH_(2)-underset(NH_(2))underset(|)(CH)-CH_(2)COOH`

Options

A. `3`-Aminoheptlenebutanal
B. `5`-Aminohex-`2`-enecarboxylic acid
C. `3`-Aminohept-`5`-enoic acid
D. `5`-Aminohept-`2`-enoic acid

Answer

To derive the IUPAC name of the given compound, we will follow a systematic approach. Here’s the step-by-step solution:

### 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 can see that there are 7 carbon atoms in the longest chain.

### Step 2: Identify the Functional Groups
Next, we identify the functional groups present in the compound. The main functional group here is the carboxylic acid (-COOH), which takes priority in naming. Additionally, there is an amine group (-NH2) and a double bond (alkene) present in the structure.

### Step 3: Number the Carbon Chain
We need to number the carbon chain in such a way that the functional groups get the lowest possible numbers. Starting from the end nearest to the carboxylic acid, we can number the carbon atoms as follows:
1. COOH (Carboxylic acid) - Carbon 1
2. CH2 (Carbon 2)
3. CH (Carbon 3, where the amine group is attached)
4. CH= (Carbon 4, where the double bond is present)
5. CH2 (Carbon 5)
6. CH2 (Carbon 6)
7. CH3 (Carbon 7)

### Step 4: Assign Locants to Functional Groups
From the numbering:
- The carboxylic acid is at position 1.
- The amine group (-NH2) is at position 3.
- The double bond (alkene) is between carbon 4 and carbon 5.

### Step 5: Construct the Name
Now we can construct the name based on the information gathered:
- The base name for a 7-carbon chain is "heptane."
- Since there is a double bond between carbons 4 and 5, we use "hept-5-ene."
- The amine group at position 3 is denoted as "3-amino."
- The carboxylic acid at position 1 is denoted as "1-oic acid."

Putting it all together, the IUPAC name of the compound is:
**3-amino-hept-5-ene-1-oic acid**

### Final Answer
The IUPAC name of the compound is **3-amino-hept-5-ene-1-oic acid**.
