CFC’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 CFC’s get into the ozone layer they are so harmful because they literally break ozone molecules down.
