The Annulenes A short note on Annulenes and aromaticity. Annulenes are monocyclic compounds with alternating double and single bonds Naming Annulenes are named using a number in brackets that indicates the ring size. Benzene is [6]annulene and cyclooctatetraene is [8]annulene Aromatic vs Non-Aromat...
Significant numbers A concept Note. Basics All measurements are approximations--no measuring device can give perfect measurements without experimental uncertainty. By convention, a mass measured to 13.2 g is said to have an absolute uncertainty of 0.1 g and is said to have been measured to the near...
