What is the main difference between displacement and double displacement reactions?
Answer and explanation
Correct answer: In displacement, one element replaces another, while in double displacement, ions exchange
In a displacement reaction, a more reactive element replaces a less reactive element in a compound, such as Zn + CuSO₄ → ZnSO₄ + Cu. In a double displacement reaction, two ionic compounds exchange ions, often forming a precipitate, water, or gas, as in AgNO₃ + NaCl → AgCl + NaNO₃. Thus option A correctly states the fundamental difference.
