Question:
Which among the following is vinylic halide?
Which among the following is vinylic halide?
Show Hint
In a vinylic halide the halogen is bonded to an sp2 carbon of a C=C double bond.
Updated On: Nov 13, 2026
\(\mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}_{2}-\mathrm{X}\)
\(\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{X}\)
\(\mathrm{CH}_{3}-\mathrm{C}\equiv \mathrm{C}-\mathrm{X}\)
\(\mathrm{C}_{6}\mathrm{H}_{5}-\mathrm{CH}_{2}-\mathrm{X}\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Vinylic halides have the C-X bond on a carbon that is part of a carbon-carbon double bond.
Step 2: Check options
A is allylic (X on sp3 carbon next to C=C). C has X on a triple-bonded carbon, an alkynyl halide. D is benzylic.\nB, \(\text{CH}_3\text{-CH=CH-X}\), has X on the double-bonded carbon.
Final Answer:
\(\text{CH}_3\text{-CH=CH-X}\) is the vinylic halide. \[ \boxed{\text{(B) }\text{CH}_{3}-\text{CH}=\text{CH}-\text{X}} \]
