Question
**Title:** Understanding Synthetic Sequences in Organic Chemistry **Question:** What is the product that results from the following synthetic sequence? **Synthetic Sequence:** 1. Starting with a cyclohexene ring. 2. Reacted with excess Br₂ in H₂O. 3. Followed by reaction with excess NaH in the presence of excess NaC≡CH and H₂O. 4. Finally treated with H₂ in the presence of Lindlar's catalyst. **Possible Products:** - **Option A:** A linear alkene with a cyclohexane ring and two terminal alkenyl groups. - **Option B:** A linear alkene with a cyclohexane ring and two adjacent hydroxyl groups. - **Option C:** A linear alkene with a cyclohexane ring and two internal alkenyl groups. - **Option D:** A linear alkene with a cyclohexane ring and two hydroxyl groups on both ends. **Choices:** - ○ A - ○ B - ○ C - ○ D In this exercise, students will analyze the steps involved in the synthetic sequence and identify the correct product by evaluating the reaction mechanisms involved, such as halogenation, alkylation, and selective hydrogenation using Lindlar’s catalyst.

**Question:** How many unique products are produced in the reaction shown? **Reaction Diagram:** - The starting compound is a cyclic structure (likely a lactone). - Reagents: 1) Excess Lithium Aluminium Hydride (LiAlH₄) 2) Water (H₂O) **Answer Options:** - ○ 1 - ○ 2 - ○ 3 - ○ 4 **Explanation:** This question involves the reduction of a cyclic ester with excess LiAlH₄ followed by hydrolysis with water, potentially leading to a diol or other reduced forms. Consider the structure of the cyclic compound and reagents used to determine the number of possible unique products.
