**Classifying Nucleophiles and Electrophiles**

In this exercise, you are tasked to classify the given chemical species by labeling each as either a nucleophile (N) or an electrophile (E). 

**Chemical Structures Presented:**
1. Top row, first structure: A carbon atom bonded to three groups—a chlorine (Cl), a positively charged carbon (C⁺), and a methyl group.
2. Top row, second structure: A cyclic structure with one of the carbons bonded to an alcohol group (OH).
3. Top row, third structure: A carbonyl group (C=O) with a positively charged carbon adjacent to it.
4. Second row, first structure (moving left to right): An ethoxide ion (ethyl group bonded to an oxygen atom with a negative charge).
5. Second row, second structure: A proton (H⁺).
6. Second row, third structure: An amine group (NH₂) bonded to an ethyl group.
7. Second row, fourth structure: A hydroxide ion (OH⁻).
8. Third row, first structure: A borane with three methyl groups and one boron atom.
9. Third row, second structure: A cyclopentadienyl anion.
10. Third row, third structure: A water molecule (H₂O).
11. Third row, fourth structure: A BH₃ molecule (borane).
12. Third row, fifth structure: An ethylene group (a double bond between two carbons, C=C).

When analyzing these structures:
- **Nucleophiles (N):** Species that donate a pair of electrons (e.g., molecules or ions with lone pairs or π bonds).
- **Electrophiles (E):** Species that accept a pair of electrons, typically featuring a region of positive charge or an electron-deficient atom (e.g., carbocations).

**Note:** By determining the electron-rich and electron-poor regions within these structures, you can categorize each species effectively.
