**Exercise 7: Chirality of Compounds**

Consider the following compounds and determine if each is chiral or achiral. Show your work by identifying whether each molecule possesses a plane of symmetry or inversion symmetry.

**a) Compound Structure:**

- The first compound is a cyclic structure featuring alternating nitrogen and carbon atoms. Two carbonyl (C=O) groups are attached to the carbon atoms.
- The stereochemistry is indicated by wedge bonds for two of the carbon atoms. 

**b) Compound Structure:**

- The second compound is a similar cyclic structure, also with alternating nitrogen and carbon atoms.
- It has substituents bromine (Br) and chlorine (Cl) attached to the carbon atoms, each specified with wedge bonds to indicate stereochemistry.

**Analysis Tips:**

1. **Chirality:** 
   - A molecule is chiral if it does not have any plane of symmetry, meaning it does not have an internal mirror plane.
   - A molecule is typically considered achiral if it has a plane of symmetry or inversion center.

2. **Identifying Symmetry:** 
   - Look for planes that can cut the molecule into two mirrored halves.
   - Check if the molecule exhibits symmetry/whether it can be superimposed onto its mirror image.

Use these principles to decide if each molecule is chiral or achiral and justify your reasoning with the symmetry observed or absent.
