SpletIn the second stage of the reaction the protonated propan-2-ol loses a water molecule to leave a carbocation (previously known as a carbonium ion) - an ion with a positive charge on a carbon atom. The carbon atom is positive because it has lost the electron that it originally contributed to the carbon-oxygen bond. http://commonorganicchemistry.com/Rxn_Pages/Alcohol_to_Halide/Bromide/PBr3.htm phil wills https://ajliebel.com
