Graded Homework Problem #12 – Answer Key Deadline : 3:00 p.m., Monday, 10/19/09 LATE WORK WILL NOT BE ACCEPTED OR GRADED!!! This problem is worth a total of 20 raw points. In parts (a) and (b) below, circle the structure of the stronger Bronsted-Lowry acid . The most acidic proton in each molecule is circled. A correct response is worth 4 points. Then, circle the structural factor that is the most important consideration when rationalizing the difference in acid strength. No additional explanation is required. Here, a correct response is worth 1 point. (a) (5 points) ELECTRONEGATIVITY ATOMIC SIZE HYBRIDIZATION RESONANCE INDUCTIVE EFFECT ELECTRONEGATIVITY ATOMIC SIZE HYBRIDIZATION RESONANCE INDUCTIVE EFFECT (b) (5 points) H 3 C N H 3 C H 3 C H H 3 C
