What happens when 2-bromo-2-chloro-3-iodo-3-fluorobutane reacts with zinc? Will it still produce alkyne?
We know vicinal tetrahalides form alkynes through reacting with zinc, but what if all those halogens in the tetrahalide compounds are different, like 2-bromo-2-chloro-3-iodo-3-fluorobutane? Will it ...

Second-Order Rate Plot is Not-Quite-Linear – Systematic Error or Mechanistic Insight?
TL;DR: A catalyzed organic reaction of A+B ->P is expected to be first order in both A and B; plotting $\mathrm{ln(\frac{A}{B})}$ vs time mostly gives a linear plot as expected, but with evident ...

What determines whether a solid-state reaction proceeds via topotactic or reconstructive mechanisms?
In solid-state chemistry, some reactions (like oxide ion insertion) preserve crystallographic relationships (topotactic), while others completely reconstruct lattices.
What experimentally measurable ...
