Greetings,

my question pertains to counting the pi electrons(N) for Huckel's rule of aromaticity...

Is it correct to just count the carbons on each double bond...

or

do i count the sides up on the whole structure.

I understand that that for it to be aromatic you use the 4N+2 and for it to be anti armatic 4N

I also unstand for it to be armatic
it has to be cyclic, and conjugated.. It has to sp2 or sp hybridized...planar...low state of energy

Youve got to visualise the orbital picture of the molecule in question, if all other criteria for aromaticity is met and you have 2,6,10,14.. pi electrons its aromatic.

i.e.



Hope this helps,

you have to count carbon atoms, which are in sp² hyibridizaton state
in this case, one Pi electron (for each carbon atom) doesn't take part in hybridization
