A proposed mechanism is shown below: (CH3)3CB1(aq) → (CH3)3C*(aq) + Br (aq) slow (CH3);C*(aq) + H20(1) (CH3)3COH2 (aq) (CH3)3COH2*(aq) fast > (CH3)3COH2 (aq) H*(aq) + (CH3)3COH(aq) fast Experimentally, a plot of In[(CH3)3CBr] vs. time gives a straight line with a slope of -0.0215 s-1 Consider the following statements, and then select the best response belov i. The overall reaction is (CH3)3CB|(aq) + H2O(1) (CH3)3COH(aq) + Br (aq) ii. The only intermediate is (CH3)3COH2*(aq). iii. The mechanism is consistent with the experimental data. O Only statement (iii) is true. O None of the statements are true. O Only statement (ii) is true. Only two statements are true. O Only statement (i) is true.
