Options

A. 1-Ethoxy-3-methoxypropane
B. Ethoxy propaneoxymethane
C. 3-Ethoxy-1-methoxypropane
D. 2, 5-Dioxyhexane

Explanation

To determine the IUPAC name of the compound `CH3OCH2CH2CH2OCH2CH3`, we can follow these steps:

### Step 1: Identify the Structure
First, we need to visualize the structure of the compound. The compound can be broken down as follows:
- `CH3O` indicates a methoxy group (−OCH3).
- `CH2CH2CH2` indicates a three-carbon chain (propyl).
- `OCH2CH3` indicates an ethoxy group (−OCH2CH3).

### Step 2: Determine the Longest Carbon Chain
Next, we identify the longest continuous carbon chain in the compound. The longest chain here consists of three carbon atoms, which corresponds to propane.

### Step 3: Identify the Substituents
Now, we identify the substituents attached to the longest chain:
- At one end of the propane chain, there is an ethoxy group (−OCH2CH3).
- At the other end, there is a methoxy group (−OCH3).

### Step 4: Number the Carbon Chain
We need to number the carbon chain to give the substituents the lowest possible numbers. Starting from the end closest to the substituent:
1. The first carbon (1) has the ethoxy group.
2. The second carbon (2) is part of the propane chain.
3. The third carbon (3) has the methoxy group.

### Step 5: Write the Name
Now we can write the IUPAC name using the substituent names and the base name:
- The ethoxy group is named first because it comes first alphabetically.
- The methoxy group comes next.
- The longest chain is propane.

Thus, the IUPAC name of the compound is **1-ethoxy-3-methoxypropane**.

### Final Answer
The IUPAC name of the compound `CH3OCH2CH2CH2OCH2CH3` is **1-ethoxy-3-methoxypropane**.
