Question

Tell whether each of the compounds below is achiral (A), chiral (C) or meso (M).

### Transcription and Explanation of Chemical Structures The image displays three distinct organic chemical structures. Below each structure, there is an empty square box. #### Left Structure - **Chemical Structure**: The molecule is a cyclobutane ring, a four-membered carbon ring. Two methyl groups (CH₃) are substituents on the ring, connected at the opposite ends of the cyclobutane. These methyl groups are shown using bold bonds indicating that they are in the upward direction relative to the plane of the ring. - **Empty Box**: The box below is empty, possibly for labeling or additional notes. #### Middle Structure - **Chemical Structure**: This molecule is a cyclopentane ring, consisting of a five-membered carbon ring. Two methyl groups (CH₃) are attached to the ring on non-adjacent carbon atoms. The bonds of the methyl groups are bold, suggesting their positions above the plane of the ring. - **Empty Box**: The box is empty, similar to the first structure, suggesting a placeholder for further information. #### Right Structure - **Chemical Structure**: The molecule contains a more complex arrangement with the following: - A Br (bromine) atom connected to a carbon atom, depicted with a bold bond indicating its position above the plane. - A hydroxyl group (OH) connected to an adjacent carbon, also in a position above the plane. - Two hydrogen atoms bonded with dashed lines, suggesting a below-the-plane position. - Additionally, a CH₃ group is bound, shown in bold. - **Empty Box**: This box, like the others, is empty and could be used for identifying or explaining the molecule. This setup, consisting of chemical structures above empty boxes, is often used in teaching organic chemistry, allowing students to label or interact with the diagrams for educational purposes such as learning stereochemistry or reaction mechanisms.

Expert Solution
Introduction

Molecules which are superimposable on their mirror image are known as chiral molecules. A Chiral molecule is a molecule whose mirror image is not superimposable on its original structure. Meso compound is a compound which has two stereogenic centers, cancelling out each other's optical activity and thus making the whole compound optically inactive
