Question

Curved arrows are used to illustrate the flow of electrons. Using the provided starting and product structures, draw the curved electron-pushing arrows for the following reaction or mechanistic step(s). Be sure to account for all bond-breaking and bond-making steps.

 

 

**Drawing Arrows in Chemical Reactions**

On the right-hand side of the image, there are two chemical structures.

1. **Structure 1 (Top Right):**
   - This is a molecule with an isopropyl group attached to a nitrogen atom that carries a positive charge (indicated by the plus sign near the nitrogen).
   - The nitrogen atom is connected to two additional isopropyl groups.

2. **Structure 2 (Middle Right):**
   - This molecule includes a lithium ion (Li^+) and a carbon framework similar to a propane structure.
   - It contains a carbonyl group (C=O) with one oxygen having a negative charge (shown by the negative charge near the oxygen).
   - Multiple hydrogen atoms are bonded to one of the carbons.

**Arrow Representation:**
- The diagram shows a black arrow pointing downward from a red-dashed box labeled “Drawing Arrows” to a chemical structure at the bottom.
  
**Overall Reaction:**
- The bottom structure shows the combination or interaction of the two reactants. The nitrogen-hydrogen bond and carbonyl oxygen are notably featured, with the lithium ion present, possibly indicating ion pairing or interaction in a reaction mechanism.

This illustration highlights the starting materials and how they rearrange or interact, central to understanding reaction mechanisms in organic chemistry.
