Red phosphorus is treated with bromine to produce PBr3. 2P + 3Br2 → 2PBr3 To prevent the formation of PBr5, an excess of phosphorus is used. The structure of Phosphorus Tribromide is a pyramidal structure with sp3hybridization. See more 1. Phosphorus tribromide (PBr3) can be used to convert primary and secondary alcohols to alkyl bromides. 2. Phosphorus Tribromide … See more The mechanism involves the electrophilic phosphorus first activating the alcohol oxygen (to form a good leaving group), followed by an SN2 substitution at the alcohol carbon. The SN2 substitution step ensures that the … See more WebQuestion 13 For a molecule of PBr3, Not yet . using the pencil tool, draw a stereochemical diagram answered . using the pencil tool, draw in bond dipoles Marked out of . using the pencil tool, draw in any resultant vectors 2.00 Flag question O Aa stroke fill bg Clear Save Picture. ...
