The IUPAC name of
`CH_3-overset(Cl)overset(|)(CH)-CH_3` is

Options

A. 2 - chloropropane
B. Chloropropane
C. 1 - chloropropane
D. 2 - chlorobutane

Answer

To determine the IUPAC name of the given compound `CH₃-CH(Cl)-CH₃`, we will follow these steps:

### Step 1: Identify the Longest Carbon Chain
First, we need to identify the longest continuous carbon chain in the structure. In this case, we have three carbon atoms connected in a straight chain.

### Step 2: Number the Carbon Chain
Next, we will number the carbon atoms in the chain. We start numbering from the end closest to the substituent (in this case, the chlorine atom). The numbering will be as follows:
- Carbon 1: CH₃
- Carbon 2: CH(Cl)
- Carbon 3: CH₃

### Step 3: Identify the Substituents
Now, we identify the substituents attached to the carbon chain. Here, we have a chlorine (Cl) atom attached to the second carbon.

### Step 4: Determine the Base Name
The base name of the compound is determined by the number of carbon atoms in the longest chain. Since there are three carbon atoms, the base name is "propane".

### Step 5: Combine the Substituent and Base Name
We need to indicate the position of the chlorine substituent. Since the chlorine is on the second carbon, we will use the prefix "2-chloro".

### Step 6: Write the Complete IUPAC Name
Combining the substituent and the base name, we get the complete IUPAC name as "2-chloropropane".

### Final Answer
The IUPAC name of the compound `CH₃-CH(Cl)-CH₃` is **2-chloropropane**.
