Sagot :

Alright, let's work through the given table systematically to extract and list the necessary information, specifically the "Name" and the "Structure" columns.

The table is structured as follows:

[tex]\[ \begin{array}{|c|c|c|} \hline \text{Name} & \text{Structure} & \text{Example} \\ \hline 1 & \text{C=O} & \text{} \\ \hline 2 & \text{[R]C([R])=O} & \text{} \\ \hline 3 & \text{C=O} & \text{} \\ \hline 4 & \text{- C - OH} & \text{} \\ \hline \end{array} \][/tex]

### Step-by-Step Extraction:

1. Extract the Names:
- The "Name" column has sequential numbers for each row:
- Row 1: Name = 1
- Row 2: Name = 2
- Row 3: Name = 3
- Row 4: Name = 4

2. Extract the Structures:
- The "Structure" column contains chemical structure representations:
- Row 1: Structure = "C=O"
- Row 2: Structure = "[R]C([R])=O"
- Row 3: Structure = "C=O"
- Row 4: Structure = "- C - OH"

### Final List:

- Names: [1, 2, 3, 4]
- Structures: ["C=O", "[R]C([R])=O", "C=O", "- C - OH"]

Thus, the structured and extracted information is:
```
Names: [1, 2, 3, 4]
Structures: ["C=O", "[R]C([R])=O", "C=O", "- C - OH"]
```

This is the detailed step-by-step solution extracting the "Name" and "Structure" columns from the given table.
