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 compound represented by `CH3-overset(Cl)overset(|)(CH)-CH3`, we will follow these steps:

### Step 1: Identify the longest carbon chain
The first step in naming an organic compound is to identify the longest continuous carbon chain. In this case, we have three carbon atoms in a straight chain.

### Step 2: Number the carbon chain
Next, we need to number the carbon atoms in the chain. We start from the end that is closest to the substituent (in this case, the chlorine atom).

- The carbon chain can be numbered as follows:
- C1: CH3
- C2: CH (with Cl attached)
- C3: CH3

### Step 3: Identify and name the substituents
In this compound, we have a chlorine (Cl) atom attached to the second carbon (C2).

### Step 4: Combine the names
Now we can combine the names of the substituents and the parent chain:
- The parent chain with three carbon atoms is called "propane".
- Since the chlorine is attached to the second carbon, we denote it as "2-chloro".

### Step 5: Write the complete IUPAC name
Putting it all together, the IUPAC name of the compound is "2-chloropropane".

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