Question

1-Chlorocyclohexene is an example of

• A. alkyl halide
• B. aryl halide
• C. benzylic halide
• D. vinylic halide
• E. allylic halide

Hint:

To remember: Vinylic is Very close to the double bond (on it), while Allylic is Away from the double bond (one carbon away).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Haloalkenes are classified based on the hybridization and environment of the carbon atom attached to the halogen.
Step 2: Key Formula or Approach:
- Vinylic halide: Halogen is attached directly to an sp{2} hybridized carbon of a C=C bond.
- Allylic halide: Halogen is attached to an sp{3} carbon adjacent to a C=C bond.
Step 3: Detailed Explanation:
1-Chlorocyclohexene consists of a cyclohexene ring where the Chlorine atom is attached to one of the carbons involved in the double bond.
Since the C-Cl bond is on the doubly bonded carbon atom (\( >C=C(Cl)- \)), it fits the definition of a vinylic halide.
Step 4: Final Answer:
It is a vinylic halide.
