In the reaction
$\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+x \mathrm{I}_{2}+6 \mathrm{OH}^{-} ightarrow \mathrm{CHI}_{3}+\mathrm{HCO}_{2}^{-}+y \mathrm{I}^{-}+5 \mathrm{H}_{2} \mathrm{O}$
the value of $x$ and $y$, respectively, are
  1. $2,1$
  2. $3,3$
  3. $4,5$
  4. $5,7$

Solution

The balancing of negative charges on both sides of the reaction suggests that the stoichiometric numbers of $\mathrm{I}_{2}$ and $\mathrm{I}^{-}$must be $4$ and $5$ , respectively.
