MCQ
The non-metal that does not exhibit positive oxidation state is
  • A
    Chlorine
  • B
    Iodine
  • ✓
    Fluorine
  • D
    Oxygen
✓

Answer

Correct option: C.
Fluorine
c
chlorine is more electronegative than iodine hence it can displace iodine from $KI$ but reverse is not possible. in $3 rd$ reaction $Zn$ is more reactive because it is above hydrogen in electrochemical series hence it will replace hydrogen. similar for $2 nd$ reaction.
