The given compound
is an example of ___________.
is an example of ___________.
- Aryl halide
- Allylic halide
- Vinylic halide
- Benzylic halide
The Correct Option is B
Solution and Explanation
The given compound is:
Step 1: Analyzing the Structure
To identify the type of compound, let’s examine its structure. The compound shown contains a halogen (Cl) attached to a carbon that is adjacent to a double bond (C=C). This arrangement is indicative of an allylic position. The key feature in this structure is that the halogen is bonded to a carbon that is adjacent to a carbon-carbon double bond. This structure defines an allylic halide.
Step 2: Understanding Allylic Halides
Allylic halides are compounds where a halogen (usually chlorine, bromine, or iodine) is attached to a carbon that is adjacent to a carbon-carbon double bond. The position of the halogen relative to the double bond makes the carbon-halogen bond weaker, which makes these compounds reactive in nucleophilic substitution reactions. \[ \text{Allylic Halide:} \quad \text{R-CH}_2\text{CH=CH}_2\text{Cl} \] The halogen in an allylic halide can be replaced by other nucleophiles in a reaction, making these compounds useful intermediates in organic synthesis.
Step 3: Conclusion
Based on the structure and the position of the halogen relative to the double bond, we conclude that the given compound is an example of an **Allylic Halide**.
Final Answer:
The given compound is an example of Allylic Halide.

Haloalkanes and Haloarenes
The hydrocarbons such as Haloalkanes and Haloarenes are the ones, in which one or more hydrogen atoms are replaced with halogen atoms. The main difference between Haloalkanes and Haloarenes is that Haloalkanes are derived from open chained hydrocarbons, also called alkanes, and Haloarenes are derived from aromatic hydrocarbons.
- Haloalkanes have hydrocarbons made up of aliphatic alkanes and one or more hydrogen atoms replaced by halogens (elements such as Chlorine, Bromine, Fluorine, Iodine, etc.) whereas, haloarenes consist of aromatic ring or rings and one or more hydrogen atoms replaced by halogens.
- In haloalkanes, the halogen atom is attached to the sp3 hybridized carbon atom of the alkyl group whereas, in haloarenes, the halogen atom is attached to the sp3 hybridized carbon atom of the alkyl group.
- Haloalkanes are saturated organic compounds where all the chemical bonds are attached to the carbon atom with single bonds and a single carbon atom is attached to the Halogen atom, whereas, the haloarenes differ from Haloalkanes by their method of preparation and properties.
- Haloalkanes are made by aliphatic alkanes by the process of free radical halogenation, whereas, haloarenes are made by direct halogenation of aromatic rings.
- Haloalkanes are odorless compounds, whereas, haloarenes have a sweet odor.
- Haloalkanes precipitate in SN2 substitution reactions, whereas, haloarenes do not precipitate in SN2 substitution reactions.
- Example of haloalkanes is CH3Cl (Methyl Chloride) and CH3CH2Br (Ethyl Bromide) and the example of haloarenes is Chlorobenzene, Bromobenzene.
