MCQ
Which of the following will not occur
- A$Fe + {H_2}S{O_4} \to FeS{O_4} + {H_2}$
- B$Cu + 2AgN{O_3} \to Cu{(N{O_3})_2} + 2Ag$
- ✓$2KBr + {I_2} \to 2KI + B{r_2}$
- D$CuO + {H_2} \to Cu + {H_2}O$
✓
Answer
Correct option: C.
$2KBr + {I_2} \to 2KI + B{r_2}$
c
(c) Electronegativity of ${I_2}$ is less than $B{r_2}$. Therefore unable to displace bromine.
(c) Electronegativity of ${I_2}$ is less than $B{r_2}$. Therefore unable to displace bromine.
