Question

considering the activity series given for nonmetals, what is the result of the below reaction? use the activity series provided. f > cl > br > i
br₂ + naf →

○ no reaction
○ na + fbr₂
○ nabr + f₂
○ na₂f + br₂

Explanation:

Step1: Recall activity series rule

For nonmetal displacement reactions, a more active nonmetal can displace a less active nonmetal from its compound. The activity series given is \( F > Cl > Br > I \), meaning F is more active than Br.

Step2: Analyze the reaction

The reaction is \( \text{Br}_2 + \text{NaF}
ightarrow \). Here, Br (in \( \text{Br}_2 \)) is less active than F (in \( \text{NaF} \)) according to the activity series (\( F > Br \)). So, Br cannot displace F from \( \text{NaF} \).

Answer:

no reaction
