Chapter 4, Problem 65E

Freon-12, ${\text{CCl}}_2{\text{F}}_2$, is prepared from ${\text{CCl}}_4$ by reaction with HF. The other product of this reaction is HCl. Outline the steps needed to determine the percent yield of a reaction that produces 12.5 g of ${\text{CCl}}_2{\text{F}}_2$ from 32.9 g of Cd4. Freon-12 has been banned and is no longer used as a refrigerant because it catalyzes the decomposition of ozone and has a very long lifetime in the atmosphere. Determine the percent yield.
