Why are haloalkanes more reactive towards nucleophilic substitution reactions than haloarenes and vinylic halides?
Advertisements
उत्तर
Haloalkanes are more reactive than haloarenes and vinylic halides because of the presence of a partial double bond character C-X bond in haloarenes and vinylic halides. Hence they do not undergo nucleophilic reactions easily.
