The main use for phosphorus tribromide is for conversion of primary or secondary alcohols to alkyl bromides, as described above. PBr3 usually gives higher yields than hydrobromic acid, and it avoids problems of carbocation rearrangement- for example even neopentyl bromide can be made from the alcohol in 60% yield. Splet24. avg. 2024 · There are a total of 26 valence electrons for PBr3. In the Lewis structure of PBr3, there are three bonding pairs of electrons and one lone pair of electrons on the central atom.
