Formal Charge: A lewis structure is used to represent the structure of a molecule. Formal charges must be minimized in a lewis structure. Negative formal charges are placed on more electronegative atoms. Answer and Explanation:1 Drawing the lewis structure for thionyl chlor...
Bond orders and formal charges are fundamental chemical descriptors. In cheminformatic applications it is necessary to be able to assign these properties to a given molecular structure automatically, given minimal input information. Here we describe a me
The first known lithiated 1-azafulvene derivatives, e.g., 8 and 13a, were generated by a low-temperature bromine–lithium exchange procedure with tert-butyllithium. These lithio species show substantial stability at ≤ 90 °C because, at these temperatures, the sterically demanding 6-diisopropyl...
