. What is displacement reaction? Explain with the help of an example
Answers
Answer:
In a displacement reaction more reactive element displaces a less reactive element to form a compound. displacement reaction can be seen in metals and non-metals both. Examples: Zinc displaces iron ions from iron sulphate solution. nickle displaces copper from copper nitrate solution.
As apparent from the name, displacement reaction, is such a reaction which results in the displacement of reactants, in such a sense that if element b is bonded with a, forming the compound:ab element b, due to the chemical energy provided to it, follow these two processes, will be followed:
firstly, the breaking of bonds it shares with element a.
secondly, the forming of "new bonds"(this is basically why bonds have to be firstly broken in the first place).
these two processes eventually result in the displacement of the reactant. usually the reactant is a compound, the individual element, or a specific part of the compound, can be displaced from its original position, through these two processes. In the example listed above, the element b, from compound ab, has been displaced from its original "bond".
Now for the second process, it depends upon the "chemical nature" of the substance to be reacting with specific other substances, meaning that element b, if has a chemical nature, to adopt a "bond" with element c, the two will now be forming a bond to result is, now, the compound : BC.
so it's literally that new bonds which can be formed apart from the present bonds, are formed, as chemical energy is provided to the substances. Further, in science, chemistry, there are two main types of displacement reactions: single and double. However, you might just want to stick with the basic definition, and basics of "displacement reaction".
usually, what causes this reaction, is that the reactivity of a specific substance, might attract any element more than, what it is bonded to.
