(4 pts) Trifluoroacetic acid (CF3CO2H: pK = 0.23) and acetic acid (CH3CO2H; pk= 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 (Ka) of acetic acid is greater than that for trifluoroacetic acid. Place your answer...
