Chapter 19, Problem 38R

To determine

To explain: The comparison and contrast between the single displacement and double displacement reactions.

Answer to Problem 38R

The reaction which involves the displacement of an atom or a set of atom by the another atom in a molecule is called the single displacement reaction while the reaction that involves the displacement of two atoms or a group of atoms by the another atom in a molecule is called the double displacement reaction.

Explanation of Solution

Introduction:

The displacement of an atom or a set of atoms is occurring in a single-displacement reaction while the displacement of two atoms or a group of atoms occurs in a double displacement reaction.

The single displacement reaction involves the displacement of a less reactive element by a more reactive element from the compound while the double displacement reaction involves the formation of new compound by exchanging the parts of two ionic compounds. The precipitation is formed in the double displacement reaction but here is no precipitation formation in a single displacement reaction except the change in color.

Conclusion:

Thus, the single displacement and double displacement reactions are different from each other.
