Reactivity of Alkyl Halides with E2 with same number of substituents in the end
I have a question regarding the reactivity of alkyl halide for E2. I know that the general rule is tertiary alkyl halide reacts the fastest with E2, and primary alkyl halide reacts the slowest.
I was ...

Why bromoacetone is more reactive towards SN2 than alkyl bromides? [duplicate]
Compare the rates towards SN2 reaction:
I got the point that 2-bromobutane d is a secondary halide, so the steric hinderance is highest making it least reactive among the four. Both b and c are ...

The dependency on electron density in the reactivity order of electrophilic and nucleophilic additions
It is well-known that for electrophilic addition across an alkene, the reactivity increases when intermediate carbocation is more stable (eg. addition of $\ce{HBr}$ or acid-catalyzed addition of $\ce{...
