ASingle displacement reactions
BDouble displacement reactions
CDisproportionation reactions
DNeutralization reactions
Answer & Solution
Correct answer: B. Double displacement reactions
1. Two dissolved ionic compounds swap partner ions.
2. This exchange is called double displacement, double replacement or metathesis.
3. Single displacement is different: there one element displaces an ion, and it is a redox change.
4. Neutralization is an acid-base reaction, not an ion exchange producing a solid.
