1 An aromatic molecule or compound is one that has special stability and properties due to a closed loop of electrons. 2  Not all molecules with ring (loop) structures are aromatic.3  A general scientific definition can be found below.or comparison, here are some molecules with ring structures that are not aromatic because they do not meet Hueckel'hÃ¼ckel S rule which requires that they have (2=n), 0 (6=n), 1 (10=n) 2 or (14=n) 3. etc-pi electrons in a: Ring MANY'pah s are extremely potent carcinogens or. mutagens
With regard to organic chemistry, chiral molecules commonly comprise a carbon atom attached to four different substituents. The substituents can be either atoms or groups of atoms, but each must differ from the other three for the carbon atom to be a chiral center (stereocenter).he left-and right-hand configurations of chiral molecules are dubbed enantiomers. Left-handed enantiomers are given the label S-for sinister in Latin-and the right-handed enantiomers are labeled R, for rectus.
