Benzaldehyde is the simplest aromatic aldehyde found in nature, consisting of a single benzene ring bearing an aldehyde group. Phylogenetically, it is one of the most widely distributed volatiles and is likely the most ancient compound given that it is produced not only by over 50% of plant fam...

Isavuconazole possesses a core structure very similar to that of other triazoles including triazole and difluorobenzene groups (Scheme 1). Isavuconazole has also a thiazolyl-benzonitrile side chain. Due to these aromatic moieties, isavuconazole possesses low solubility in water, which is a significant ...
And in C if we polarize the bonds and perform resonance it seems like a benzene ring is formed,so would this be aromatic? WhatsApp-Image-2019-09-26-at-1.58.56-PM-ConvertImage.jpg(19.59 kB, 1040x403 - viewed 172 times.) Logged ...
