The IUPAC name of `{:(H_(3)C-CH-C_(3)H_(7)),(" |"),(" "OC_(3)H_(7)):}` is

Options

A. 4-propoxy pentane
B. pentyl-propyl ether
C. 2-propoxy pentane
D. 2-pentoxy propane

Explanation

To determine the IUPAC name of the compound `{:(H_(3)C-CH-C_(3)H_(7)),(" |"),(" "OC_(3)H_(7)):}`, we will follow these steps:

### Step 1: Identify the structure
The given structure consists of a carbon chain with an ether functional group. The ether is represented by the `-O-` linkage between two alkyl groups.

### Step 2: Identify the alkyl groups
- The left side of the ether linkage has a propyl group (C3H7).
- The right side of the ether linkage has a butyl group (C4H9).

### Step 3: Determine the longest carbon chain
The longest carbon chain in the structure is the butyl group, which consists of four carbon atoms.

### Step 4: Name the alkyl groups
- The propyl group will be named as "propoxy" because it is the smaller alkyl group.
- The butyl group will be named as "butane" because it is the larger alkyl group.

### Step 5: Number the carbon chain
We need to number the carbon chain starting from the end closest to the ether oxygen to give the lowest possible number to the substituent:
- The butyl group will be numbered from the end closest to the ether oxygen.

### Step 6: Combine the names
The IUPAC name is formed by combining the names of the alkoxy group and the longest carbon chain:
- The name will be "propoxy" (from the propyl group) and "butane" (from the butyl group).

### Final IUPAC Name
Thus, the final IUPAC name of the compound is **"2-propoxybutane"**.
