Q1. Show how the following compound can be prepared, starting with cyclopentane.
Background
Topic: Radical Reaction Synthesis
This question tests your understanding of multi-step organic synthesis, specifically using radical halogenation, elimination, and nucleophilic substitution to transform cyclopentane into a methoxy-substituted cyclopentene.
Key Terms and Formulas
Radical Halogenation: Introduction of a halogen atom (e.g., Br) to an alkane via a radical mechanism.
E2 Elimination: Removal of a halogen and a hydrogen to form an alkene.
Nucleophilic Substitution (SN2): Replacement of a halogen with a nucleophile (e.g., methoxide).

Final Answer:
The compound can be synthesized from cyclopentane by: (1) radical bromination, (2) E2 elimination to cyclopentene, (3) allylic bromination with NBS, and (4) SN2 substitution with methoxide.
This sequence efficiently introduces the methoxy group at the allylic position of cyclopentene.
