Note that later (more recent) printings of a text may contain fewer errors as they are (hopefully) fixed with each printing.
How can I tell which printing my text is?
| Text Page # | Error Description |
| 8 | Answer to problem 1.4a is incorrect in the back of the book. The answer given for chlorine is actually the electron configuration for bromine. The electron configuration for chlorine is not given at all. |
| 19 |
Problem 1.18a. Missing CH2 in answer in Solutions Guide. Answer should be CH3NHCH2CH2CH3. |
| 60 | Problem 1.58f. In Solutions Guide answer, the structure for nitrate has an extra electron pair on the double-bonded oxygen. |
| 91 | Problem 2.22e has a wrong answer in the back of the book, p. A-25. Correct answers: diethylpropylamine and N,N-diethyl-1-propanamine) |
| 91 | Problem 2.22f has the wrong answer in the Study Guide (p 67). Correct answers: no common name and N-ethyl-3-methylcyclopentanamine) has is listed as cyclohexanamine. |
| 157 | Problem 3.47a asks for configurational isomers of 2-methyl-2,3-hexadiene in 1st printing (no configurational isomers possible) and 2-methyl-2,4-hexadiene (which could be E or Z at the 4-5 double bond) in 2nd printing. However, Study Guide on p. 96 gives structures for 3-methyl-2,4-hexadiene, which can be E or Z at both of the double bonds. At least the names listed under the structures in the Study Guide are correct for the structures shown--just not for the problem as posed. |
| 181 | Problem 4.22d. Second answer (oxymercuration-demercuration) should use MeOH, not EtOH |
| 210 | Problem 5.12a. Answer should be ID, not enantiomers. Both are R. |
| 229 | Problem 5.37b. Answer should be (2S,3S). |
| 364 | Problem 8.18 should refer to an SN1 reaction |
| 515 | Figure 12.2. M+1 peak should have an intensity (relative abundance) of 1.02, rather than 0.52 |
| 539 | Problem 12.23a has wrong answer in Study Guide.
Correct answer is that C=O stretch wavenumbers decrease in order H2C=O > CH3CH=O > (CH3)2C=O). Also, Study Guide says "...two alkyl groups has the largest wavenumber" when it should say smallest. |
| 612 | Problem 13.39. Answer is wrong for #3 and #5. #3-Two signals, from left (higher ppm) to right-doublet and quartet. #5-Three signals, from left (higher ppm) to right-doublet, doublet, quartet |
| 615 | Problem 13.41d. Solutions Guide indicates that structure could be cyclohexene as well as (the correct answer of) 3-hexene, but this is not possible given that the formula of the compound is C6H12 |
| 652 | Structure of benzaldehyde is incorrect (structure shown for benzaldehyde is actually benzoic acid, PhCO2H). The OH in the structure should be replaced with an H, giving PhCHO for benzaldehyde. |
| 1027 | Second paragraph. This method, as finally admitted in this edition, doesn't work for all amino acids (see problem 22.12). Averaging the two pKa values for the amino acid going from net charge = +1 --> 0 and from net charge = 0 --> -1 will work for all amino acids. |

Look at the page after the title page. Near the bottom, under the publisher's logo and immediately above the ISBN number is a line that reads "Printed in the United States of America." Right under that line is a list of numbers, starting with "10" and going in reverse numerical order. The lowest number is the printing number. In the example below, the numbers go down to one, so it is the first printing. If the numbers went from "10" to "3" then it would be the third printing. Higher printings are more recent and, in theory, should contain fewer errors. This is something to keep in mind when purchasing a used textbook! The example below is actually from the fourth edition of the text, but the idea is the same.
