It has attracted attention as a source of hydrogen fuel, but is otherwise … See more Learn about the structure, valence electrons, formal charge, lone pairs, hybridisation and shape of NH3BF3, a chemical compound of ammonia trifluoroborane.7. The colourless or white solid is the simplest molecular boron-nitrogen-hydride compound. In order to calculate the formal charges for NH3 we'll use the equationFormal charge = [# of valence electrons] - [nonbonding val electrons] - [bonding elect Hint: \[N{H_3}\] is electron rich as it has a lone pair and \[B{F_3}\] is electron deficient, due to this, ammonia donates its electron pair to \[B{F_3}\] , which has vacant orbital that takes up electrons and completes its octet by forming a coordinate bond and changing its hybridisation. It is sp2 hybridized. The sum of the formal charges of each atom must be equal to the overall charge of the molecule or ion. JANZEN. Sintesi. Suggest Corrections. Which theory explains it?
