Question

 Complete the following electron-dot structure for Methylphenidate (C14H19NO2), showing the position of any multiple bonds and lone pairs.

The image depicts the structural formula of caffeine, a well-known stimulant found in coffee, tea, and many energy drinks. 

### Detailed Explanation of the Diagram:

1. **Atoms:**
   - **Carbon (C):** Represented by the lines connecting other atoms. Each carbon atom can form four bonds.
   - **Hydrogen (H):** Attached to carbon atoms, notated with a single line indicating a single bond.
   - **Nitrogen (N):** Present in the structure, forming bonds with carbon and hydrogen.
   - **Oxygen (O):** Double-bonded to a carbon atom.

2. **Rings and Chains:**
   - **Heterocyclic Rings:** The structure contains two fused rings. 
     - One ring is composed of five atoms (including nitrogen), known as an imidazole ring.
     - The other ring is a six-membered ring with two nitrogen atoms, known as a pyrimidine ring.

3. **Functional Groups:**
   - **Amide Group:** The structure includes an amide functional group with a carbon double-bonded to an oxygen atom (C=O) and single-bonded to a nitrogen atom.

Caffeine's molecular formula is C₈H₁₀N₄O₂, indicating it contains 8 carbon atoms, 10 hydrogen atoms, 4 nitrogen atoms, and 2 oxygen atoms. This compound has psychoactive properties, which can increase alertness and reduce fatigue in certain doses.
