Xenon hexafluoroplatinate is the product of the reaction of platinum hexafluoride with xenon, in an experiment that proved the chemical reactivity of the noble gases.This experiment was performed by Neil Bartlett at the University of British Columbia, who formulated the product as "Xe + [PtF 6] −", although subsequent work suggests that Bartlett's product was probably a salt mixture and did ...
Spartan applies computational chemistry methods (theoretical models) to many standard tasks that provide calculated data applicable to the determination of molecular shape conformation, structure (equilibrium and transition state geometry), NMR, IR, Raman, and UV-visible spectra, molecular (and atomic) properties, reactivity, and selectivity.
Arsenic pentafluoride can be prepared by direct combination of arsenic and fluorine: [3] 2As + 5F 2 → 2AsF 5. It can also be prepared by the reaction of arsenic trifluoride and fluorine: AsF 3 + F 2 → AsF 5. or the addition of fluorine to arsenic pentoxide or arsenic trioxide. 2As 2 O 5 + 10F 2 → 4AsF 5 + 5O 2 2As 2 O 3 + 10F 2 → 4AsF 5 ...
A molecular model is a physical model of an atomistic system that represents molecules and their processes. They play an important role in understanding chemistry and generating and testing hypotheses .
A plastic ball-and-stick model of proline. In chemistry, the ball-and-stick model is a molecular model of a chemical substance which displays both the three-dimensional position of the atoms and the bonds between them. [1] The atoms are typically represented by spheres, connected by rods which represent the bonds.
Fluorine-19 nuclear magnetic resonance spectroscopy (fluorine NMR or 19 F NMR) is an analytical technique used to detect and identify fluorine-containing compounds. 19 F is an important nucleus for NMR spectroscopy because of its receptivity and large chemical shift dispersion, which is greater than that for proton nuclear magnetic resonance ...
Electrochemical fluorination (ECF), or electrofluorination, is a foundational organofluorine chemistry method for the preparation of fluorocarbon-based organofluorine compounds. [1] The general approach represents an application of electrosynthesis .
His model predicts that F donates electrons into a vacant atomic orbital in the atom it is bonded to, giving the bonds a certain amount of sigma bond character. In addition, the fluorine atom also receives a certain amount of pi electron density back from the central atom giving rise to double bond character through (p-p)π or (p-d)π "back ...
