MCQ
For the reaction in aqueous solution $Z{n^{2 + }} + {X^ - } \rightleftharpoons Zn{X^ + },$ the ${K_{eq}}$ is greatest when $X$ is
- ✓${F^ - }$
- B$NO_3^ - $
- C$ClO_4^ - $
- D${I^ - }$
✓
Answer
Correct option: A.
${F^ - }$
(a) Because of ${F^ - }$is a highly electronegative. So it is easily lose the electron and reaction occur rapidly.
