Chapter 5, Problem 5.37P

Interpretation Introduction

(a)

Interpretation:

The given molecule is same or different enantiomer of the shown original molecule is to be identified.

Concept introduction:

Isomers are molecules having same connectivity. Enantiomers are nonsuperimposable mirror images. If the molecules can be interconverted by one or more single bond rotation, then they are said to be the same enantiomer or identical molecules. If the molecules are not able to interconvert, then they are enantiomers of each other.

Answer to Problem 5.37P

The given molecule is not same enantiomer as the original one.

Explanation of Solution

The given original enantiomer is:

The molecule which is to be compared is:

The given molecule is the non superimposable mirror image of THE original molecule.

These molecules cannot be interconverted by single bond rotation. Hence, the given molecule is not same enantiomer as the original one.

Conclusion

The molecule is not a same enantiomer as the original molecule is determined on the basis of capability of interconversion by single bond rotation.
