Answer to Question 1
FALSE
Answer to Question 2
The Montreal Protocol and its amendments have limited the production of freons. Instead, halofluorocarbons (HFCs) and halochlorofluorocar bons (HCFCs) have been adopted. Neither type of molecule transports significant amounts of Cl to the stratosphere, as HCFCs are eliminated in the troposphere by OH radicals, and HFCs do not have Cl in the molecule.
