Transcribed Image Text:**Retrosynthetic Analysis Exercise**
**Objective:**
Perform the retrosynthetic analysis for the indicated bond and choose the correct synthetic equivalents.
**Target molecule:**
A structure with a methoxy group (MeO) attached to a carbon chain. The oxygen attached to the MeO group has lone pairs.
**Synthetic Pathway Options:**
**A:**
- Left Component: A methoxylated carbon fragment with lone pairs on oxygen.
- Right Component: Sodium methoxide (NaOMe).
**B:**
- Left Component: A non-methoxylated carbon double-bonded to oxygen with lone pairs.
- Right Component: Sodium methoxide (NaOMe).
**C:**
- Left Component: A carbon double-bonded to oxygen, followed by a chain, with lone pairs on oxygen.
- Right Component: Sodium hydroxide (NaOH).
**D:**
- Left Component: A methoxy group (OMe) attached to a positively charged carbon double-bonded to oxygen with lone pairs.
- Right Component: Sodium hydroxide (NaOH).
**Answer Options:**
- ○ A
- ○ B
- ○ C
- ○ D
**Instructions:**
Select the correct option that represents the synthon for the target molecule based on the bond indicated in the retrosynthetic analysis.

**Reactant Structure:**
- Structure of a branched alkane with an alcohol group on the end.
**Product Options:**
- **A.** A branched alkane similar to the reactant, with an alcohol group at the same position.
- **B.** A ketone group replacing the alcohol.
- **C.** An aldehyde group positioning one carbon away from a methyl group.
- **D.** A structure with both ketone and alcohol groups.
**Multiple Choice Answers:**
- ○ A
- ○ B
- ○ C
- ○ D
**Explanation:**
The reaction involves an oxidation process where the alcohol group may convert into a carbonyl group. Choose the correct product based on the oxidation level of the reactant and the given reagents.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F26456894-b92c-484d-bb74-bc37d60095a8%2Fd4a09816-dabe-41c2-9546-dde940cb4c0c%2Fbzst0x_processed.jpeg&w=3840&q=75)
