The IUPAC name of `CH_(3)CH_(2)OCH(CH_(3))_(2)`is :

Options

A. isopropoxyethane
B. 2-methoxybutane
C. 1-methyl-1-methoxyethane
D. 2-Ethoxypropane

Explanation

To determine the IUPAC name of the compound `CH3CH2OCH(CH3)2`, we can follow these steps:

### Step 1: Identify the Structure
The given molecular formula can be broken down into its structural components. The compound consists of:
- A chain of carbon atoms
- An ether functional group (indicated by the presence of an oxygen atom between carbon chains)

### Step 2: Draw the Structure
From the formula `CH3CH2OCH(CH3)2`, we can draw the structure:
- The first part `CH3CH2` represents an ethyl group (2 carbon atoms).
- The `O` indicates that this is an ether.
- The `CH(CH3)2` indicates a carbon atom bonded to two methyl groups (making it a propyl group).

Putting this together, the structure looks like this:
```
CH3
|
CH3-CH-O-CH2-CH3
|
CH3
```

### Step 3: Identify the Longest Carbon Chain
In this structure, we can see that there are three carbon atoms in the longest continuous chain. This is the propyl part of the molecule.

### Step 4: Name the Ether
In IUPAC nomenclature for ethers, we name the alkyl groups attached to the oxygen atom and add the word "ether." In this case:
- The ethyl group (from `CH3CH2`) is attached to the oxygen.
- The propyl group (from `CH(CH3)2`) is the longest chain.

### Step 5: Assign the Position of the Ether
Since the ethyl group is attached to the second carbon of the propyl chain, we will indicate this in the name. The correct way to name this compound is:
- The longest chain is propyl (3 carbons).
- The ethyl group is attached at the second position.

Thus, the IUPAC name of the compound is **2-ethoxypropane**.

### Final Answer
The IUPAC name of `CH3CH2OCH(CH3)2` is **2-ethoxypropane**.
