Allylic halides are

Answer

**Step-by-Step Solution:**

1. **Definition of Allylic Halides:**
Allylic halides are organic compounds that contain a halogen atom (such as fluorine, chlorine, bromine, or iodine) bonded to a carbon atom that is adjacent to a carbon-carbon double bond (C=C).

2. **Structure of Allylic Halides:**
In terms of hybridization, the carbon atom to which the halogen is attached is typically sp³ hybridized. This means that it is bonded to four other atoms, including the halogen and possibly hydrogen or other carbon atoms.

3. **Identification of Allylic Carbon:**
The carbon atom that is directly bonded to the halogen is referred to as the allylic carbon. It is important to note that this carbon is adjacent to the carbon that is part of the double bond.

4. **Examples of Allylic Halides:**
For example, consider the structure of an allylic halide:
- If we have a double bond between two carbon atoms (C=C), and one of the carbons has a halogen (X) attached to it, this compound is classified as an allylic halide.
- An example structure could be CH2=CH-CH2X, where X is a halogen.

5. **Conclusion:**
Therefore, allylic halides can be summarized as compounds where a halogen is bonded to an sp³ hybridized carbon that is adjacent to a carbon-carbon double bond.
