MCQ
Which of the following is correct statement?
- A$F_2$ has higher dissociation energy than $Cl_2$
- ✓$F$ has higher electron affinity than $Cl$
- C$HF$ is stronger acid than $HCl$
- DBoiling point increases down the group in halogens
✓
Answer
Correct option: B.
$F$ has higher electron affinity than $Cl$
b
$2 KBr + I _2 \rightarrow 2 KI + Br _2$
$2 KBr + I _2 \rightarrow 2 KI + Br _2$
This reaction is not possible because $Br ^{-}$ion can't be oxidized to $Br _2$ with $I _2$ as $I _2$ can't oxidize bromine since $Br _2$ is a better oxidizing agent than iodine.
