Question

X + YZ → XZ + Z is a form of ______________

(a) combination reaction

(b) displacement reaction

(c) disproportionate reaction

(d) decomposition reaction

I had been asked this question in final exam.

I'm obligated to ask this question of Redox Reactions and Electrode Processes in section Redox Reactions of Chemistry – Class 11

Answer 1

Right answer is (b) displacement reaction

The explanation is: In a displacement reaction, a metal or a non-metal, in a compound can be displaced by another metal in the uncombined state. So the above reaction X + YZ → XZ + Z, is a displacement reaction.
