MCQ
Chlorine cannot displace
  • ✓
    Fluorine from $NaF$
  • B
    Iodine from $NaI$
  • C
    Bromine from $NaBr$
  • D
    None of these
✓

Answer

Correct option: A.
Fluorine from $NaF$
a
(a) $C{l_2} + NaF\, \to \,{\rm{No\, reaction}}$

Since $C{l_2}$ is less electronegative then ${F_2}$. Therefore unable to displace fluorine from its salt.
