Question
Caffeine is the active ingredient in coffee, tea, and some carbonated beverages. Add lone pairs, as needed, to the structure of caffeine.

The given image presents an editing toolbar and a skeletal chemical structure of caffeine. Below is a detailed analysis of the content:

### Toolbar:
- **Select:** An option likely used to select elements or bonds in the drawing interface.
- **Draw:** Allows the user to draw elements or chemical bonds.
- **Templates:** Access to predefined structures for ease of drawing.
- **More:** Presumably contains additional options and tools.
- **Erase:** To delete elements or bonds.

### Chemical Elements and Bonds:
- Buttons for types of bonds: single, double, and triple bonds.
- Elements representing common atoms in organic chemistry: **C** (Carbon), **N** (Nitrogen), **O** (Oxygen), **H** (Hydrogen).

### Structure of Caffeine:
The skeletal formula shows caffeine's arrangement of atoms. Here's a description of the structure:

- **Ring Structure:** 
    - Caffeine has a fused ring structure composed of two rings: a six-membered and a five-membered ring.
- **Atoms and Bonds:**
    - The structure comprises Carbon (C), Nitrogen (N), and Oxygen (O) atoms.
    - Double bonds (represented by double lines) and single bonds (single lines) connect these atoms.
- **Methyl Groups (CH3):**
    - There are two CH3 (methyl) groups attached to the nitrogen atoms in the six-membered ring.
    - Another CH3 group is attached to the nitrogen in the five-membered ring.
- **Functional Groups:**
    - The structure includes amide groups (C=O and NH) as part of the six-membered ring.
    - Each ring is interconnected through these functional groups.
    
### Graphical Elements:
- **Navigation Icons:**
    - Zoom icons are, presumably, used to enlarge or reduce the view of the diagram.
    - Undo/Redo icons provide options to revert or reapply recent changes.

This molecular structure illustrates the complexity and specific arrangement of atoms that define caffeine, benefiting students in visualizing and understanding chemical compositions. For a complete understanding, lone pair electrons must be added where necessary, particularly on nitrogen and oxygen atoms, to fulfill valency requirements.
