But what exactly is a hybr...Phosphorus tribromide is a chemical compound of phosphorus and bromine. It is used in the manufacture of pharmaceuticals such as alprazolam, methohexital and fenoprofen. It is also a potent fire suppression agent marketed under the name PhostrEx. Bromine is a halogen element with the symbol Br and atomic number 35.1. From a theoretical viewpoint we would expect the Br to be sp3 hybridized, because in the HBr molecule the Br atom has 4 pairs of electrons around it (the 3 lone pairs plus the bonding pair), and symmetry (plus the repulsion of electrons for each other) tells us to expect that 4 pairs of electrons arrange themselves in a tetrahedron, …PBr3 and SOCl2; SOCl2 Mechanism For Alcohols To Alkyl Halides: SN2 versus SNi; Nucleophilic Acyl Substitution (With Negatively Charged Nucleophiles) ... not trigonal planar; the energetic “penalty” for losing a leaving group on an sp 2 hybridized atom is considerably less for the heavier, more polarizable sulfur than it is for carbon ...Phosphorus pentabromide is a reactive, yellow solid of formula P Br 5, which has the structure [PBr4]+ Br − (tetrabromophosphonium bromide) in the solid state but in the vapor phase is completely dissociated to PBr3 and Br2.
