why cs toh reactions no H2O, but have HI ? whereas KSChan's
reactions have H2O, and I-
and the stoichiometric ratio all different
iodoform reactions need memorise? which one to memorise?all?
Only if you can't intelligently balance it out yourself (it's a
redox reaction after all, so you should be able to work out the
coefficients yourself using half-equations), then memorize the
coefficients. Yes, all.
CS Toh's equation occurs first to generate HI, then since OH- is
in excess, all the HI will undergo Bronsted-Lowry acid-base proton
transfer reaction to generate Chan Kim Seng's equation. Better to
write Chan Kim Seng's equation in the A levels.
