Chapter 23.1, Problem 7LC

Interpretation Introduction

Interpretation: To draw the structural formula and IUPAC name of all possible di-chloropropanes.

Concept Introduction: The structural formula is used to represent the atoms of a chemical compound. It is the way of representing the chemical compound and chemical proportions of an atom using symbols of elements. It is also used to show the molecular arrangement of atoms.

Answer to Problem 7LC

Isomers are formed when a substitution reaction involving chlorine and propane takes place.

The structural formula along with the IUPAC name is as below:

1. 
2. 
3. 
4. 

Explanation of Solution

When a substitution reaction involving chlorine and propane happens, isomers of Di chloropropane are formed. 4 isomers can be formed when this reaction happens, they are:

1. 1,1-dichloropropane
2. 1,2-dichloropropane
3. 1,3-dichloropropane
4. 2,2-dichloropropane

Conclusion

4 isomers are formed and all of them are stated above. The isomers are the possible structures that can be formed during the reaction. The IUPAC nomenclature is given based on the longest carbon chain and the position of the chlorine group.
