    Question

    A displacement (single replacement) reaction will occur when…

    1. A more reactive metal displaces a less reactive metal from its compound.
    2. A less reactive metal displaces a more reactive metal from its compound
    3. Displacement only occurs when two of the same metals are reacted
    4. Displacement reactions will only occur in metals above iron in the reactivity series

    hintHint:

    One element is replaced by another in a compound in a single displacement reaction, which is also known as a single replacement reaction. This type of chemical reaction is an oxidation-reduction reaction.

    The correct answer is: A more reactive metal displaces a less reactive metal from its compound.

      A displacement (single replacement) reaction will occur when a more reactive metal displaces a less reactive metal from its compound.
      • During the single replacement reaction, the position of the elements present in the compounds will be shifted. And the replacement reaction takes place in the ions.
      • And here, the less reactive element will be replaced by the more reactive elements.
      • The replacement reaction is mainly in two types, replacement reaction, and double replacement reaction.
