Chapter 22, Problem 15STP

Interpretation Introduction

Interpretation: To identify the molecular structure of cis isomer.

Concept Introduction: Stereoisomers are molecules that have the same number of carbon atoms but differ in the arrangement of atoms.

The two categories of stereoisomers are as follows:

• Cis-trans isomers
• Enantiomers

Answer to Problem 15STP

The molecular structure that represents a cis isomer is (C).

Explanation of Solution

The geometric isomers in which the atoms are joined in the same order are known as cis isomers while the isomers in which the arrangement of atoms is in a different order or on the opposites of the double bond are known as trans isomers.

The given molecular structure of the cis isomer is represented as follows:

  

Conclusion

Thus, the molecular structure that represents a cis isomer is (C).
