CFCโ€™s are so harmful to the ozone layer because they literally break ozone molecules (O3) apart. When UV light from the sun hits a CFC molecule a Carbon-Chlorine bond breaks and a Chlorine atom is produced. This Chlorine atom is quite reactive and so it reacts with an ozone molecule. It forms Chlorine Oxide and Oxygen (02). So when CFCโ€™s get into the ozone layer they are so harmful because they literally break ozone molecules down.
