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 ...

Equation for reaction between chlorine fluoride and potassium bromide
The equation given in the answer key was
$$\ce{ClF + 2KBr → KCl + KF + Br2}$$
However won't the $\ce{KCl}$ also react with $\ce{ClF}$ to form $\ce{KF}$ and $\ce{Cl2}$, resulting in the net reaction ...

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 ...
