Answer :
C is the answer. Reasons being that, two elements from both side of the reactant switches side to form two new compounds. On the other hand, A , B and D involves one element displacing the other to produce a new compound.
Answer:
The correct answer is option C.
Explanation:
Double displacement reaction is defined as the reaction in which exchange of ions takes place to give a product.
[tex]AB+CD\rightarrow CB+AD[/tex]
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.
[tex]AB+C\rightarrow CB+A[/tex]
From all the given options the reaction which is classified as Double displacement reaction is :
[tex]2AlBr_3 + 3K_2SO_4\rightarrow 6KBr + Al_2(SO_4)_3[/tex]
Where as other reactions are the examples of Single displacement reaction.
