Webcarbon–halogen bond involves an sp2 carbon orbital, whereas an alkyl carbon–halogen bond involves an sp3 carbon orbital. Hence, a vinylic carbon–halogen bond has more s character. Recall that bonds with more s character are stronger (Eq. 14.26, p. 664). Consequently, it takes more energy to break the carbon–halogen bond of a vinylic halide. WebYes.
