CHEM 2311 Midterm: CHEM 2311 GT Examp5iii
Document Summary
Copies of tables 2. 7, 9. 1, and 9. 2 are attached. You may use a calculator on this exam. Atomic masses: h, 1. 008; c, 12. 01; o, 15. 999: (32 points) circle the letter on the right which corresponds to the answer to each question. Ff: (24 points) (i) (4 points each) provide a single molecular structure consistent with the following data. The ir spectra have a number of peaks, only the most relevant are provided. Ir: 3520 (broad), 3400 (broad), 3050 cm-1 (and others) Note: parts (a)-(i) are worth two points each, (j) is worth one point. Each part is graded independently, without reference to other answers. Analysis of ir spectrum (in conjunction with formula) Analysis of the 13c nmr spectrum (in conjunction with ir and sodar) Is there a peak arising from a carbonyl in the 13c nmr spectrum? (circle one) yes no.
