JEE MainChemistryp Block Elements (Group 15, 16, 17 & 18)
Which of the following reactions produces an interhalogen compound that yields a halite ion upon complete hydrolysis?
Options
- AReaction of Cl ₂ with equal volume of F ₂
- BReaction of Cl ₂ with excess of F ₂
- CReaction of Br ₂ with excess of F ₂
- DReaction of I ₂ with excess of F ₂
Correct answer
B. Reaction of Cl ₂ with excess of F ₂
Step-by-step solution
The hydrolysis of interhalogen compounds ( XX '_n ) yields a halide ion ( X '^- ) and an oxoanion of the larger halogen ( X ). The type of oxoanion depends on the oxidation state of X in the interhalogen: - XX ' hypohalite ( XO ^- ) - XX '₃ halite ( XO ₂^- ) - XX '₅ halate ( XO ₃^- ) - XX '₇ perhalate ( XO ₄^- ) To obtain a halite ion, the interhalogen must be of the type XX '₃ . Evaluating the given reactions: 1) Reaction of Cl ₂ with equal volume of F ₂ produces ClF (type XX ' ), which yields a hypohalite ion. 2)
