(CH₃)₄N⁺ is neither an electrophile nor a nucleophile because of it:

1.	Does not have an electron pair for donation and it also 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.
