Br2 + NaF Right arrow. Which best completes the chemical equation?

No reaction

Explanation:

Chemical equation:

Br₂ +  NaF   →   no reaction

There is no reaction between bromine and sodium fluoride.

Reason:

When bromine is allowed to react with sodium fluoride no reaction occur because fluorine is more reactive than bromine. Bromine can not displace the fluorine in order to form a bond with sodium.

Reactivity of halogen:

As we move from top to bottom the atomic number of halogen elements increases. As the atomic number increase their reactivity decrease. So fluorine is more reactive than the other members.
