Assume that a compound is a cyclic, planar, completely conjugated ring. Which number of p electrons would make it aromatic? a) 0 p electrons
b) 2 p electrons
c) 3 p electrons
d) 4 p electrons
e) 32 p electrons

2 p electrons.

Explanation:

For any compound to be considered an aromatic compound it must be cyclic,flat, conjugated and it must obey Huckel's rule that states an aromatic compound must have 4n + 2 pi electrons in it's p orbitals for it to be an aromatic compound.

n can represent an integer from 2, 6,10, 14,

The lone pair is actually in a pure 2p orbital perpendicular to the ring, which means they count as π electrons.
