(CH3)4N+ is neither an electrophile nor a nucleophile because it:
| 1. | does not have an electron pair for donation as well as cannot attract an electron pair. |
| 2. | neither has an electron pair available for donation nor can accommodate electrons since all shells of N are fully occupied. |
| 3. | can act as Lewis acid and base. |
| 4. | none of the above. |
