Explanation

To determine the structural formula of ethyl ethanoate, we can follow these steps:

### Step 1: Identify the Functional Group
Ethyl ethanoate is an ester, as indicated by the suffix "-oate" in its name. Esters are characterized by the functional group -COO-.

**Hint:** Look for the suffix in the name to identify the functional group.

### Step 2: Break Down the Name
The name "ethyl ethanoate" can be broken down into two parts:
- "Ethyl" refers to the ethyl group (C2H5 or CH2CH3).
- "Ethanoate" refers to the ethanoate part derived from acetic acid (CH3COO-).

**Hint:** Understand the components of the name to identify the groups involved.

### Step 3: Construct the Structure
1. Start with the ethyl group (C2H5):
- This can be represented as CH2CH3.

2. Next, consider the ethanoate part:
- Ethanoate is derived from acetic acid (CH3COOH), which gives the structure CH3COO-.

3. Combine these two parts:
- The ethyl group (C2H5) will attach to the carbonyl carbon (C=O) of the ethanoate group.

The overall structure can be represented as:
```
O
||
CH3-C-O-CH2-CH3
```

### Step 4: Finalize the Structural Formula
The complete structural formula of ethyl ethanoate is:
```
CH3
|
CH3-C-O-CH2-CH3
```

### Summary
The structural formula of ethyl ethanoate is:
```
CH3
|
CH3-C-O-CH2-CH3
```
