  2. B \(x = F , Cl , Br\) तथा \(y = F , Cl , Br , I\)
  3. C \(x = Cl , Br , I\) तथा \(y = F , Cl , Br , I\)
  4. D \(x = F , Cl , Br , I\) तथा \(y = F , Cl , Br , I\)

Answer & Solution

Correct Answer

(A) \(x = F , Cl , Br , I\) तथा \(y = F , Cl , Br\)

Step-by-step Solution

Detailed explanation

\(\underset{\text { (Unstable) }}{2 FeI _{3}} \longrightarrow \underset{\text { (Stable) }}{2 FeI _{2}}+ I _{2}\) Due to strong reducing nature of \(I^{-}\) \(2 Fe ^{3+}+2 I ^{-} \longrightarrow 2 Fe ^{2+}+ I _{2}\)
