MCQ
When iodine reacts with $NaF,$ $NaBr$ and $NaCl$
  • A
    It gives mixture of ${F_2},$ $C{l_2}$ and $B{r_2}$
  • B
    It gives chlorine
  • C
    It gives bromine
  • ✓
    None of these
✓

Answer

Correct option: D.
None of these
d
(d) $\left. \begin{gathered}
  {I_2} + NaF\,\,\xrightarrow{{}} \hfill \\
  {I_2} + NaBr\,\,\xrightarrow{{}} \hfill \\
  {I_2} + NaCl\,\,\xrightarrow{{}} \hfill \\ 
\end{gathered}  \right\}\,\,No\,\,reaction$

Because $I_2$ is least electronegative among halogens.
