IUPAC name of compound `CH_(3)CH_(2)Ooverset(O)overset(||)(C )CH_(2)CH_(2)CH_(3)` is

Options

A. Propyl propanoate
B. Ethyl butanoate
C. Propyl butanoate
D. Ethyl propanoate

Explanation

To determine the IUPAC name of the compound `CH3CH2O(C=O)CH2CH2CH3`, we will follow these steps:

### Step 1: Identify the Functional Group
The compound contains an ester functional group, which is characterized by the presence of a carbonyl group (C=O) adjacent to an ether (R-O-R').

### Step 2: Identify the Alkyl Groups
In the given structure, we can identify the two alkyl groups:
- The alkyl group attached to the oxygen (O) is an ethyl group (C2H5 or CH3CH2-).
- The alkyl group attached to the carbonyl (C=O) is a butyl group (C4H9 or CH3CH2CH2CH2-).

### Step 3: Number the Carbon Chain
We will number the carbon chain starting from the end closest to the functional group:
1. Start from the carbon connected to the oxygen (O).
2. Number the chain:
- 1: Ethyl group (O-CH2)
- 2: Carbonyl carbon (C=O)
- 3: CH2
- 4: CH2
- 5: CH3 (the terminal carbon of the butyl group)

### Step 4: Naming the Alkyl Groups
- The ethyl group (C2H5) will be named first.
- The butyl group (C4H9) will be named second.

### Step 5: Combine the Names
The IUPAC name of the ester is formed by combining the names of the alkyl groups and adding the suffix "-oate" to the name of the carboxylic acid derived from the butyl group:
- Ethyl (from the ethyl group) + Butanoate (from butanoic acid) = Ethyl Butanoate.

### Step 6: Finalize the IUPAC Name
Thus, the complete IUPAC name of the compound is **Ethyl Butanoate**.

### Summary
The IUPAC name of the compound `CH3CH2O(C=O)CH2CH2CH3` is **Ethyl Butanoate**.
