Question

What is the deciding factor for single displacement reaction?

• A. Transition metal list
• B. Halogen series list
• C. Reactivity series
• D. Formative series

Answer 1

The correct option is C

Reactivity series

For any single displacement reaction, the deciding factor for the reaction to go through or end in no reaction state is the reactivity series of metals and non-metals. Elements (metals) placed higher in the series can displace the cation and get oxidised. The displaced cation goes through reduction.
