The s-type orbital is polar, while the p-type orbital is nonpolar. The ring current of an aromatic compound is the same as that of a diamagnetic compound, and thus, aromatic compounds can be distinguished by their ring current. how to add microsoft keyboardWebContents Section 1: Vocabulary Section 2: Determining Aromaticity Section 3: Conjugation and Aromaticity Section 4: Resonance and Aromaticity Section 5: Frequently Asked Questions Section 6: Common Errors ... is an aromatic molecule; Practice Problems: Determine whether or not the following molecules are aromatic.
