To analyze the given mono-alcohol and determine its empirical formula, structural formula, and name, we follow these steps:

### Step 1: Determine the Empirical Formula

Given percentages:
- %C = 60%
- %H = 13.33%
- %O = 26.67%

Convert these percentages to grams assuming a 100 g sample:
- C: 60 g
- H: 13.33 g
- O: 26.67 g

Convert grams to moles using atomic masses:
- Moles of C: \(\frac{60}{12} = 5\) moles
- Moles of H: \(\frac{13.33}{1} = 13.33\) moles
- Moles of O: \(\frac{26.67}{16} = 1.67\) moles

Find the simplest whole number ratio:
- Ratio of C : H : O = 5 : 13.33 : 1.67

To simplify, divide each by the smallest number of moles (1.67):
- C: \(\frac{5}{1.67} ≈ 3\)
- H: \(\frac{13.33}{1.67} ≈ 8\)
- O: \(\frac{1.67}{1.67} = 1\)

Thus, the empirical formula is \( C_3H_8O \).

### Step 2: Structural Formula and Name

#### Part A: Empirical Formula
- The empirical formula of the mono-alcohol is \( C_3H_8O \).

#### Part B: Structural Formula and Name
- The structural formula of a mono-alcohol with the empirical formula \( C_3H_8O \) can be either of the following:
  - **Propanol (Propan-1-ol):** \( CH_3-CH_2-CH_2-OH \)
  - **Isopropanol (Propan-2-ol):** \( CH_3-CH(OH)-CH_3 \)

#### Part C: Name of the Alcohol
Since it is a primary alcohol (mono-alcohol), it can be either:
- **Propanol (Propan-1-ol)** or
- **Isopropanol (Propan-2-ol)**.

For a primary alcohol, Propanol is \( CH_3CH_2CH_2OH \), and for a secondary alcohol, Isopropanol is \( CH_3CH(OH)CH_3 \).

Given it is a mono-alcohol, Propanol (Propan-1-ol) is more likely.

### Summary
1. **Empirical Formula:** \( C_3H_8O \)
2. **Possible Structural Formulas:**
   - Propan-1-ol: \( CH_3-CH_2-CH_2-OH \)
   - Propan-2-ol: \( CH_3-CH(OH)-CH_3 \)
3. **Name:**
   - Primary Alcohol: Propanol (Propan-1-ol)
   - Secondary Alcohol: Isopropanol (Propan-2-ol)
