(iii) hydrogen, (iv) chlorine

Options

A. (i) and (ii)
B. (ii) and (iii)
C. (iii) and (iv)
D. (i) and (iv)

Explanation

To determine the heteroatoms present in the compound \( CH_3-CH_2-O-CH_2-CH_2Cl \), we will identify the elements in the compound and classify them as either heteroatoms or not.

### Step 1: Identify the elements in the compound
The given compound is \( CH_3-CH_2-O-CH_2-CH_2Cl \). From this structure, we can identify the following elements:
- Carbon (C)
- Hydrogen (H)
- Oxygen (O)
- Chlorine (Cl)

### Step 2: Define heteroatoms
Heteroatoms are defined as atoms in a molecule that are not carbon or hydrogen. In organic compounds, the most common heteroatoms include oxygen, nitrogen, sulfur, and halogens (like chlorine, bromine, etc.).

### Step 3: Classify the identified elements
Now, we will classify the identified elements:
- **Carbon (C)**: This is not a heteroatom.
- **Hydrogen (H)**: This is also not a heteroatom.
- **Oxygen (O)**: This is a heteroatom.
- **Chlorine (Cl)**: This is a heteroatom.

### Step 4: List the heteroatoms
From our classification, the heteroatoms present in the compound are:
- Oxygen (O)
- Chlorine (Cl)

### Conclusion
Thus, the heteroatoms present in \( CH_3-CH_2-O-CH_2-CH_2Cl \) are oxygen and chlorine.

### Final Answer
The heteroatoms present in the compound are:
(i) Oxygen
(iv) Chlorine
