Question

Why is Cl2 + KI → KCl + 12 not a synthesis reaction?

A) Oxygen is not a product in this reaction.
B) The reaction has more than one product.
C) Oxygen is not a reactant in this reaction.
D) The reaction has more than one reactant.

Answer 1

B) The reaction has more than one product.

Step-by-step explanation:

• Synthesis reactions are one type of chemical reaction that occurs when two or more elements or smaller compounds occur to form a single large compound.
• Therefore, the reaction Cl₂ + 2KI → 2KCl + I₂ is not a synthesis reaction because more than one product is formed.
• Instead, it is an example of a single replacement reaction where a more reactive element displaces a less reactive element from its salt.
