IUPAC name of the compund `CH_3-underset(CH_3)underset(|)"CH"-OCH_3`is

Options

A. 1-methyoxy-1-methylethane
B. 2-methoxy-2-methylethane
C. 2-methoxypropane
D. isorproplmethyl ether.

Explanation

To find the IUPAC name of the compound \( CH_3-CH(CH_3)-O-CH_3 \), we can follow these steps:

### Step 1: Identify the Structure
The given compound can be represented as:
- A central carbon atom with a hydroxyl group (O) and two alkyl groups attached to it.
- The structure can be drawn as follows:

```
CH3
|
CH- O - CH3
|
CH3
```

### Step 2: Determine the Longest Carbon Chain
In the structure, we need to identify the longest continuous carbon chain. The longest chain here consists of three carbon atoms, which can be seen as:
- \( CH_3-CH-CH_3 \) (the central carbon is connected to the ether oxygen).

### Step 3: Identify the Alkoxy Group
The smaller alkyl group attached to the oxygen is a methyl group (\( CH_3 \)). This will be named as the alkoxy group.
- The alkoxy group here is methoxy (\( O-CH_3 \)).

### Step 4: Naming the Compound
According to IUPAC nomenclature for ethers, the name is derived from the alkoxy group and the longest carbon chain:
- The longest chain is propane (3 carbon atoms).
- The methoxy group is attached to the second carbon of the propane chain.

Thus, the name of the compound is:
- **2-methoxypropane**

### Final Answer
The IUPAC name of the compound \( CH_3-CH(CH_3)-O-CH_3 \) is **2-methoxypropane**.
