The IUPAC name of the compound is :-
`H-undersetunderset(O)("||")C-(CH_(2))_(2)-undersetunderset(H-C=O)(|)(CH)-(CH_(2))_(2) - undersetunderset(O)("||")C-H`

Options

A. 1,4,7 - Triheptanal
B. 1,3,5-Triformyl pentane
C. 3-Formyl heptene dial
D. 1,3,5-Pentene tricarbaldehyde

Answer

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

### Step 1: Draw the Structure
The compound is represented in a condensed form. We need to expand this to visualize the structure. The condensed formula indicates that there are two aldehyde groups and a five-carbon chain. The structure can be drawn as follows:

```
O
||
H-C-CH2-CH-CH2-C-H
| |
O O
||
H-C
```

### Step 2: Identify the Longest Carbon Chain
The longest continuous carbon chain in the structure consists of 5 carbon atoms. Therefore, the parent chain is pentane.

### Step 3: Identify the Functional Groups
The functional groups present in the compound are aldehyde groups (-CHO). In this case, there are three aldehyde groups attached to the carbon chain.

### Step 4: Determine the Naming of the Functional Groups
When naming aldehyde groups in IUPAC nomenclature, we replace the suffix "-e" of the alkane with "-al". However, since the aldehyde carbons are not included in the parent chain, we use the term "carbaldehyde" instead.

### Step 5: Count the Number of Functional Groups
There are three aldehyde groups, which will be indicated by the prefix "tri-". Therefore, we will use "tricarbaldehyde" for the three aldehyde groups.

### Step 6: Number the Carbon Chain
To give the aldehyde groups the lowest possible numbers, we will number the carbon chain from one end to the other. The positions of the aldehyde groups are at carbon 1, carbon 3, and carbon 5.

### Step 7: Write the Complete IUPAC Name
Combining all the information, we can write the complete IUPAC name as:
**1,3,5-pentane-tricarbaldehyde**

### Final Answer
The IUPAC name of the compound is **1,3,5-pentane-tricarbaldehyde**.
