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 it technically inaccurate to say that the decrease in reactivity of halogens is due to decreasing electronegativity?
I came across the following information in this post.
Below the infographic there is a paragraph with a disclaimer:
As another disclaimer, the reactivity of the halogens decreasing down the group ...

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 silver nitrate chemical test more favorable than that of sodium iodide?
Two tests to determine the presence of alkyl chlorides are the silver nitrate in 1% ethanol and sodium iodide in 15% acetone tests. These two tests both produce a precipitate when added to chloride ...

Why doesn't fluoride ion have highest nucleophilic power (nucleophilicity)?
As you can see from the image above,
'$\ce{R3C}$' anion has 1 lone pair
'$\ce{R2N}$' anion has 2 lone pairs
$\ce{RO}$ anion has 3 lone pairs
$\ce{F}$ anion has 4 lone pairs
According to VSEPR theory,...
