Question

Which of the following would represent a single displacement reaction between Potassium Bromide (K^+Br^-) and Iodine (I), which forms iodide (I^-)?
options:
KBr + I -> K + IBr
KBr + I -> KBr + I
KBr + I -> KI + Br

Answer 1

Answer:

Option : KBr + I -> KBr+I

Explanation:

Single-replacement reaction or single displacement reactions are a type of chemical reactions in which a whole compound reacts with an element in such a way that the element takes place of one of the compound's own elements and sets it free.

If we talk about KBr and I displacement reaction is not possible among these because Iodine is less reactive than Bromine that is why it will not react with KBr or replace Br.

                       KBr + I -> KBr+ I

Potassium Bromide + Iodine -> Potassium bromide + Iodine
