Question: Which one of the following reaction is not possible [MP PMT 1991]
Options:
A) $ Fe+H_2SO_4,\to FeSO_4+H_2 $
B) $ Cu+2AgNO_3,\to ,Cu,{{(NO_3)}_2}+2Ag $
C) $ 2KBr+I_2,\to 2KI+Br_2 $
D) $ CuO+H_2,\to Cu+H_2O $
Show Answer
Answer:
Correct Answer: C
Solution:
According to the reactivity series Iodine is less reactive than Potassium. Therefore Iodine cannot displace Potassium from KBr.So $2KBr + I_2 → 2KI + Br_2$ will not occur.
