Ethanol (C2H5OH) can be converted into the much more reactive and useful precursor material chloroethane, C2H5Cl, by treating it with phosphorus trichloride, PCl3, according to the following equation.
3 C2H5OH + PCl3 → 3 C2H5Cl + H3PO3
If 28.23 g C2H5OH is treated with excess PCl3 and produces 27.11 g C2H5Cl, what is the percent yield?
