Ch 5 : E2 mechanism

Reactivity order : (CH 3) 3 C- > (CH 3) 2 CH- > CH 3 CH 2 - > CH 3 - In an E2 reaction, the reaction transforms 2 sp 3 C atoms into sp 2 C atoms. This moves the substituents further apart decreasing any steric interactions. So more highly substituted systems undergo E2 eliminations more rapidly.

why does the reactivity of halogens decreases …

Therefore, the halogen reactivity decreases down the group due to the fact the atomic radius increases and shielding increases down the group as the molecules get bigger as they contain more electron shells, so the attraction between the incoming electron theyre trying to GAIN and the positive nucleus in weaker, so they are unable to attract the electron as easily as higher up halogens which
