`CH_2Br–CH_2-CH_2` Br is a vicinal dihalide. True/False

Answer

To determine whether the compound \( CH_2Br–CH_2–CH_2 \) is a vicinal dihalide, we need to follow these steps:

### Step 1: Understand the Definition of Vicinal Dihalide
A vicinal dihalide is a compound that has two halogen atoms (in this case, bromine, Br) attached to adjacent carbon atoms in the carbon chain.

### Step 2: Analyze the Given Compound
The given compound is \( CH_2Br–CH_2–CH_2 \). We can break it down as follows:
- The first carbon (C1) has a bromine atom attached to it.
- The second carbon (C2) is connected to C1 and has no halogen attached.
- The third carbon (C3) is connected to C2 and also has no halogen attached.

### Step 3: Identify the Position of Halogens
In this compound:
- The bromine atom is attached to the first carbon (C1).
- There are no bromine atoms on the second (C2) or third (C3) carbon.

### Step 4: Determine if the Compound is Vicinal
For a compound to be considered a vicinal dihalide, there must be halogen atoms on adjacent carbon atoms. In this case, since C1 has a Br and C2 has none, they are not adjacent halogenated carbons. Thus, the compound does not meet the criteria for being a vicinal dihalide.

### Conclusion
Since the compound \( CH_2Br–CH_2–CH_2 \) does not have bromine atoms on adjacent carbon atoms, the statement that it is a vicinal dihalide is **False**.
