can someone help me understand this?
from what I understand, for something to be aromatic, it has to have 3 things, 1) must follow the 4n+2 rule 2) be planar 3) have a closed loop (meaning all sp2 carbons)
How can you tell if something is going to be planar? Isn't that synonymous w/having sp2 carbons, or do anions and cations make a difference.
Also, if something is ANTIaromatic, it follows the same thing as aromatic except its 4n?
and nonaromatic is everything that doesn't follow these rules?
I really am lost as to how to draw molecular orbitals and then be able to tell if its aromatic or not...also, sometimes the answers will say, "its non aromatic because the internal H's prevent planarity"...how do you know if the H's are internal?
Ok, if anyone wants to help me out, I'd really appreciate it...mechanisms I understand, but this stuff I really don't
