Explain how the Lewis structure of ozone is important. What can chemists can do to prevent ozone depletion in the atmosphere? Why is ethanoic acid considered an acid? Why is TiCl4 considered an acid? Does H3PO4 exhibit resonance? Explain. Explain why the second deprotonation for Oxalic acid...
The structure of sialyl Lewis X is shown below as Formula A. The present invention provides a class of linkable sialyl Lewis X analogs of structural Formula 1. These analogs have a conjugatable nucleophilic amino group, which facilitates preparation of multimeric SLeX compositions with enhanced bindi...
These complexes had a cage-shaped structure around a boron center. The geometry of the structure determined the properties of the borates in which ligands were consistently bound to the metal center by chelation. Theoretical calculations suggested that the cage-shaped borates had a large dihedral ...
