In chemistry, mesoionic compounds are one in which a heterocyclic structure is dipolar and where both the negative and the positive charges are delocalized. A completely uncharged structure cannot be written and mesoionic compounds cannot be represented satisfactorily by any one mesomeric structure. Mesoionic compounds are a subclass of betaines. Examples are sydnones and sydnone imines (e.g. the stimulant mesocarb), münchnones, and mesoionic carbenes. The formal positive charge is associated with the ring atoms and the formal negative charge is associated either with ring atoms or an exocyclic nitrogen or other atom. These compounds are stable zwitterionic compounds and belong to nonbenzenoid aromatics. (Wikipedia).
This organic chemistry video tutorial explains how to draw a meso compound and how to identify them. Meso compounds are achiral molecule with chiral centers. They have an internal plane of symmetry and are superimposable images. Meso compounds are optically inactive and they are identic

Stereochemistry: Meso Compounds, Diastereomers
Meso soup! Here we will see how compounds with multiple stereocenters may be achiral overall, if they have an internal plane of symmetry (meso compounds) or an inversion center. In addition, we will define and discuss diastereomers. Now where's that soup... Watch the whole Organic Chemist

Nomenclature of Polycyclic Compounds: Naphthalene, Biphenyl, Anthracene, Spiro, Bicyclo
We've done tons of IUPAC nomenclature for simple molecules, but once we start introducing multiple rings, things get trickier. This is especially the case because there are so many ways to get multiple rings. They can be fused, they can be bicyclic, aromatic or aliphatic, and every type ha

Compound Frequencies (continuous vs. discrete)
Two ways to look at this: start with a given rate (10% in this example) and use different compound frequencies, which gives different final (terminal values). Or, assume the same terminal value, and translate into different discrete interest rates (e.g., monthly, daily). But, the discrete
