Question:
Arrange the following halides in decreasing order of their reactivity towards dehydrohalogenation:
Arrange the following halides in decreasing order of their reactivity towards dehydrohalogenation:
Show Hint
Dehydrohalogenation reactions are influenced by the stability of the resulting product and the ease with which the leaving group departs.
Updated On: Mar 6, 2026
- B>D>A>C
- B>D>C>A
- D>B>C>A
- D>B>A>C
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Reactivity in dehydrohalogenation increases with the availability of a more stable leaving group and the ability to stabilize the resulting alkene.
Thus, D>B>C>A.
