Question

what is the end product when friendship reacts with PBr3

Answer 1

$\huge{\mathcal\red{♡Answer:}}$

PBr3 + 3C2H5OH → 3C2H5Br + H3PO. Phosphorus(III) bromide react with ethanol to produce bromoethane and phosphorous acid

In the "activation” step, the alcohol is converted into a good leaving group by forming a bond to P (O-P bonds are very strong) and displacing Br from P [note that this is essentially nucleophilic substitution at phosphorus].
