I want the b part only thank u ## Arrow Pushing in Chemical Reactions### Question 4Analyze the arrow pushing mechanism for the following reactions:#### Part a:1. **Structure Sequence**: - A cyclohexanol derivative with a substituent undergoes a reaction sequence. - Initially, dehydration occurs to form a carbocation. - Water adds to the carbocation, forming a new alcohol. - This process is reversible.2. **Key Steps**: - **Carbocation Formation**: Involves the loss of a water molecule, resulting in a stable carbocation. - **Rearrangement**: Methyl or hydride shifts may occur to form a more stable carbocation. - **Reiteration of Steps**: The reaction is reversible with water acting as a nucleophile, converting the carbocation back to an alcohol.3. **Notes**: - *Annotations highlight potential rearrangements and unstable intermediates such as carbocations.*#### Part b:1. **Reaction Overview**: - A linear chain with a terminal halide reacts with sodium amide (NaNH₂). - The resulting product is an ether in a cyclic structure, alongside sodium chloride.2. **Mechanism**: - **Intermolecular SN2 Reaction**: The amide acts as a nucleophile. - **Cyclization**: The negatively charged intermediate facilitates the formation of a six-membered ring.3. **Notes**: - *Annotations suggest optimization between a 5 or 6-membered ring formation for stability.*### Diagram Explanation- **Structural Representations**: Molecular structures are depicted with arrows indicating electron movement during reactions.- **Rearrangements**: Highlighted adjustments in electron distribution to achieve more stable configurations. This explanation supports understanding complex organic mechanisms, with detailed focus on electron flow and structural rearrangements.
