The pyridine molecule is a planar and cyclic shape, similar to a regular hexagon. It has a nitrogen atom in the center and five carbon atoms connected to it, forming a ring.
Heterocyclic compounds may be aromatic (3 double bonds in the cyclic structure) or nonaromatic.
In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties. His rule states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic.
CO32- is trigonal planar, bond angles are 1200
Planar Systems was created in 1983.
Square planar
If maleic anhydride were planar, then it would actually be ANTIaromatic, because one of the lone pairs on the cyclic oxygen would participate in the cyclic pi-bonding. For this reason, maleic anhydride is NOT planar. The cyclic oxygen actually sticks out about .3 Angstroms, which breaks antiaromaticity. So, short answer: no.

No. There are two molecular requirements that must be met to indicate aromaticity. In order to be aromatic a molecule must: 1) have a ring of pi electrons above and below the molecule. This means: a. The molecule must be cyclic. b. All atoms in the ring must be sp2 hybridized c. The molecule must be planar. 2) have an odd number of pairs of pi electrons. Since acetic acid is not cyclic, it cannot meet the first requirement and therefore cannot be aromatic. There are, however, delocalized electrons that increase the stability of the compound.

The molecular geometry of the compound CO32- is trigonal planar. It has a single atom of carbon bound to three atoms of oxygen.
If you mean hard surface by polygon. Then organic modeling is modeling things that are alive like trees and people and hard surface modeling is modeling cars and anything planar. Both can be modeled with polygons but usually organic models will be converted to subdivision meshes
