Select an approximate region where aromatic ring stretches occur in FTIR spectra (cm-1).
a.) Alkene b.) Alkyne c.) Carboxylic acid d.) ester e.) ether
The instructions were to define if the molecule was aromatic or antiaromatic. If the element (such as N or O) has a double bond directly on it, then its lone pair doesn't count in the conjugation system; if there's a single bond, then its lone pair is counted. I counted the electrons on the lone pairs, and since the total was 6 e-, I labeled it as aromatic. was this correct?
