Question

(Please see attached image for skeleton structure): "Classify the compound below as aromatic, antiaromatic, or nonaromatic. Explain your answer." A.) has a nitrogen with one lone pair inside the ring; the nitrogen is attached to a hydrogen and there are 2 double bonds inside the ring B.) There are 3 double bonds inside the ring and a +charge on one carbon (carbocation) C.) there are 5 double bonds inside this structure D.) there are 4 double bonds inside this structure 1) classify the cimpunnd below as aromatic ntiaromatic, or nonaromatie. Explain your answer. (5 pts) CH,

Explanation / Answer

Aromaticity Rules :

Anti aromaticity Rules :

Same rules as Aromaticity but 4n electrons

A - Non-aromatic ---> No conjugation [or resonance inside the ring]

B - Aroamtic --> [ 6 pi electrons = 4n+2 form and fully conjugated one ]

C - Aromatic --> [ 10 pi electrons = 4n+2 form and fully conjugated one ]

D - Anti aromatic ---> [ 8 pi electrons = 4n form and fully conjugated one ]

E - Aroamtic one ----> [ 6 pi electrons including lone pair on oxygen and conjugated system ]
