Explanation:

Florine has the highest electronegativity and it thus pulls the element of groups in the COOH group towards itself, making it relatively easy to loose the proton of the carboxyl group.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
