Explain Huckel's Rule

A structure can only be an aromatic if the number of electrson of the ring is 2, 6, 10, 14, 18.

What are the two criteria that need to be meat to be an aromatic

1.) Compound must have a ring comprised of continuously overlapping p orbitals

2.) Huckel's rule needs to be followed

If a compound does not have overlapping p orbitals what is it called

Nonaromatic

If a compound has overlapping p orbitals but does not follow Huckel's rule what is it called?

Antiaromatic

cyclopentadienyl anion (aromatic)

Tropylium cation (aromatic)

Pyridine

Is pyridine a _____

Basic because the lone pair is not part of the conjugated p orbitals

Pyrrole

Pyrrole____

Is going to be an acid because it is it needs its one pair to have conjugated p orbitals

How Does an aromatic with a carbon chain become a benzoic acid?

Na2Cr2O7, H2SO4, H2O

Birch reaction

What reagents do you need for a birch reaction?

Na, CH3OH, NH3 (l)

how do EWG and EDG effect birch reactions

The double bond will go on the EDG and the not on the EWG

When is 1,4 adduction favored

Under thermodynamic conditions

When is 1,2 adduction favored

Under kinetic conditions
