The name of the compound `CH_(3)-CH_(2)-CHO` is

Options

A. propanal
B. propanone
C. ethanol
D. ethanal

Explanation

To determine the name of the compound `CH₃-CH₂-CHO`, we can follow these steps:

### Step 1: Identify the Structure
The given compound `CH₃-CH₂-CHO` can be broken down as follows:
- `CH₃` is a methyl group.
- `CH₂` is a methylene group.
- `CHO` is the aldehyde functional group.

### Step 2: Count the Carbon Atoms
Count the number of carbon atoms in the compound:
- There are 3 carbon atoms in total: one from `CH₃`, one from `CH₂`, and one from `CHO`.

### Step 3: Determine the Functional Group
The `CHO` group indicates that this compound is an aldehyde. Aldehydes have the general formula R-CHO, where R is a hydrocarbon chain.

### Step 4: Name the Carbon Chain
Since there are 3 carbon atoms, the base name of the compound will be derived from propane (the alkane with 3 carbon atoms).

### Step 5: Add the Suffix for Aldehyde
For aldehydes, we replace the suffix "-e" of the alkane name with "-al". Therefore, propane becomes propanal.

### Final Answer
The name of the compound `CH₃-CH₂-CHO` is **propanal**.
