Reactivity order of halides for dehydrohalogenation is
Text Solution
Verified by ExpertsThe correct answer is:
B
atomic radii
belongs to the same group
orderly Atomic radii go on increasing as the nuclear charge increases in preceeding downwards in a group. The decreasing order of bond length
. The order ofbond dissociation energy
During dehydrohalogenation C‐I bond breaks more easily than C‐F bond. So reactivity order of halides is,
