8. (4 pts. total; 2 pts. each) in the space provided below, explain the following atomic properties. Be succinct. Electronegativity (X) Polarizability 9. (4 pts) Trifluoroacetic acid (CF3CO2H; pka = 0.23) and acetic acid (CH3CO2H;pka = 4.75) are monoprotic acids (meaning they can dissociate only one H ion/molecule of acid). Using your knowledge of structure, explain why the acid dissociation (K) of acetic acid is greater than that for trifluoroacetic acid. Place your answer in the space provided.
