**Q2 Relationships**

(Wade 5-30) Give the stereochemical relationships between each pair of structures. Examples are same compound, structural isomers, enantiomers, diastereomers.

**Diagrams:**

(a) Two Fischer projections of molecules with CH₃ (methyl groups) at the ends and OH (hydroxyl groups) and H (hydrogen atoms) on the horizontal bonds. The arrangements of OH and H differ between the two structures.

(b) Two Fischer projections of similar structures with CH₂OH and OH groups. Arrangements differ, indicating different stereochemistry.

(c) Two Fischer projections with CH₃ groups and OH groups, arranged differently on the carbon chain.

(d) Two 3D representations with tetrahedral centers, showing atoms like CH₃, Cl (chlorine), Br (bromine), and H. Different spatial arrangements suggest different stereochemistry.

(e) Two cyclohexane chair forms with OH, CH₃, and Br substituents. Different groups are positioned axially and equatorially.

(f) Two cyclohexane chair forms with one having CH₃ and H groups arranged differently on the ring structure.

**Note:** Analyze each pair's 3D spatial arrangement to determine their stereochemical relationships.
