Answer 1

Aromatic molecules are cyclic, conjugated, have (4n+2) pi electrons, and are flat. Anti-aromatic molecules are cyclic, conjugated, have (4n) pi electrons, and are flat. Non-aromatic molecules are every other molecule that fails one of these conditions.

Answer 2

PYRIDINE

(C) pyridine is aromatic, flat with bond angle of 120 degrees.

GETTING TO KNOW MORE ABOUT PYRIDINE:

* Pyridine has the chemical formula C5H5N and is a basic heterocyclic organic molecule. It has a similar structure to benzene, but one of the methyne groups (=CH) has been substituted with a nitrogen atom.

* It's a highly flammable, slightly alkaline, water-miscible liquid with an obnoxious fish-like odor. Pyridine is colorless, however it can look yellow in older or impure samples.

* Many essential molecules, such as agrochemicals, medicines, and vitamins, include the pyridine ring. Pyridine was traditionally made from coal tar.

* The molecule is electron deficient due to the electronegative nitrogen in the pyridine ring. As a result, it undergoes electrophilic aromatic substitution processes less readily than benzene derivatives.

* As a result, pyridine is more susceptible to nucleophilic substitution, as indicated by the ease with which strong organometallic bases may metalize it.
