Use Huckels rule to predict aromaticity

•	Determine which of the following compounds are aromatic. Examine the structures to see whether or not they are planar and fully conjugated. Justify your answers with some electron counting:

•	tetra-t-butyl-cyclobutadiene (TBUCBD10)

•	naphthalene (NAPHTA12)

•	cyclohepta-1,3,5-triene (CHMOCO01)

•	cyclopentadienyl anion (NARGET)

•	(14)annulene (FANNUL)

•	(16)annulene (ANNUL01)

•	(18)annulene (ANULEN)

•	pyridine (PYRDNA01)
