Question

In a single displacement reaction, the ______ reactive metal displaces the ______ reactive metal from its compound.

• A. more, less
• B. less, more
• C. less, non
• D. non, less

Answer 1

The correct option is A more, less

In a single displacement reaction, the more reactive metal displaces the less reactive metal from its compound.
Example: $\text{Zn(s)}+2\text{HCl(l)}\to {\text{ZnCl}}_2\text{(aq)}+{\text{H}}_2\text{(g)}$
Here, zinc being more reactive displaces hydrogen from hydrochloric acid.
