The IUPAC name of `C_(2)H_(5)O C_(2)H_(5)`

Options

A. Diethyl ether
B. Ethoxy ethane
C. Ethoxy propane
D. Dimethyl ether

Answer

To find the IUPAC name of the compound with the formula `C2H5O C2H5`, we can follow these steps:

### Step 1: Identify the Structure
The formula `C2H5O C2H5` can be broken down into its components:
- `C2H5` corresponds to an ethyl group (CH3-CH2-).
- The `O` indicates the presence of an oxygen atom, which suggests that this compound is an ether.

### Step 2: Write the Structural Formula
The structural formula can be represented as:
```
CH3
|
CH3-CH2-O-CH2-CH3
```
This shows that we have two ethyl groups connected by an oxygen atom.

### Step 3: Determine the Parent Chain
In this case, both sides of the ether have ethyl groups. Since both groups are the same, we can use the term "diethyl" to describe the two ethyl groups.

### Step 4: Name the Ether
According to IUPAC nomenclature for ethers, the name is derived from the alkyl groups attached to the oxygen. Since we have two ethyl groups, the name will be "diethyl ether".

### Step 5: Finalize the IUPAC Name
Thus, the IUPAC name of the compound `C2H5O C2H5` is **diethyl ether**.

### Summary of the Steps:
1. Identify the components of the formula.
2. Write the structural formula.
3. Determine the parent chain and alkyl groups.
4. Name the ether based on the alkyl groups.
5. Finalize the IUPAC name.
