Why can't RX add to alkenes / alkynes like HX?
With an analogous mechanism: C bonded to X has a δ+ charge and attacks the pi electrons to form a carbocation intermediate, with X- as a leaving group. X- then adds to the carbocation to neutralize it....

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 ...

Why is the reactivity of primary alkyl halides with nucleophiles (SN2 mechanism) greater than secondary and tertiary alkyl halides?
For the reaction between alkyl halide and a nucleophile, following the SN2 mechanism, the reactivity of alkyl halides is in the order: primary halide > secondary halide > tertiary halide.
If you ...
