Questions 1. Given the H NMR spectrum and molec- ular formula for each of the following compounds, deduce the structure of the compound, estimate the chemical shifts of all its protons using the parameters in Tables 22.3–22.5, and assign the NMR sig- nals to their respective protons. (a) C.H,,Cl; 1H NMR (CDC12): 8 3.33 (2H, s); 1.10 (9H, s) (b) C-H,,0,; 1H NMR (CDC12): 8 3.88 (1H, s); 2.25 (3H, s); 1.40 (6H, s) (C) CH,,0,; 1H NMR (CDC1,): 8...
Use Table 8.1, a computer, or a calculator to answer the following. Suppose a candidate for public office is favored by only 47% of the voters. If a sample survey randomly selects 2,500 voters, the percentage in the sample who favor the candidate can be thought of as a measurement from a normal curve with a mean of 47% and a standard deviation of 1%. Based on this information, how often (as a %) would such a survey show that...
