Here's what I get  

Explanation:

In a single replacement reaction, one element must displace another element from its compound.

Thus, we must consider the reactivity series, because an element lower down in the series cannot replace one that is above it.

In a double replacement reaction, the cations change partners with the anions. All we need consider are the solubilities of the new cation-anion partners.

In a single replacement reaction, it is mandatory that one element displaces the other according to their reactivity on the reactivity series.

On the other hand, In a double- displacement reaction; the cations just exchange anions and vice versa.

An example of a single displacement reaction is;

  • A reaction between HCl and Na metal where Na+ ion displaces H+ ion as a result of higher reactivity.

An example of a double displacement reaction is;

  • A reaction between NaOH and HCl to form H2O and NaCl.

As such, there's no preference in double displacement reactions as ions are swapped.
