Question

Example of vinylic halide is

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is A

Step 1. Understanding Vinyl Halide: Vinyl halides are compounds in which a halogen atom is directly attached to an sp² hybridized aliphatic carbon atom, which forms part of a double bond.

Step 2. Examine Each Structure: Option (1): Contains a halogen attached to an sp² hybridized carbon in a double-bonded system, classifying it as a vinyl halide. Option (2): Represents an allyl halide, with the halogen attached to an sp³ hybridized carbon adjacent to a double bond. Options (3) and (4): Both structures are aryl halides, with the halogen attached to an aromatic ring.

Step 3. Conclusion: Option (1) is the correct example of a vinyl halide.

Answer 2

A vinylic halide is an organic compound where a halogen atom is directly bonded to a carbon-carbon double bond. This is different from allylic halides, where the halogen is bonded to a carbon adjacent to the double bond.

Let's examine the options to identify the vinylic halide:

1. Option 1:This option shows a halogen directly attached to a carbon-carbon double bond, which is the characteristic feature of a vinylic halide.
2. Option 2:This compound has the halogen attached to a saturated carbon, and not directly on the carbon-carbon double bond, so it is not a vinylic halide.
3. Option 3:This option does not show a halogen attached to a double-bonded carbon, thus it is not a vinylic halide.
4. Option 4:Similar to Option 2, this also has a halogen attached to a carbon that is saturated, indicating it's not a vinylic halide.

Based on the analysis, the correct answer is Option 1, where we see the halogen directly bonded to the carbon-carbon double bond, confirming it as a vinylic halide.
