Assertion (A): Use of Chlorofluorocarbons (CFC’s) is hazardous to environment. Reason (R): CFC’s are very reactive, flammable and toxic gases.
A is correct but R are not correct.
CFC’s are responsible for depletion of ozone layer. Hence it is hazardous to environment. But they are non-reactive, non-flammable and non-toxic gases. That’s why they are used in refrigerators.
