Why is the expected stretching absorption of the C=O bond 1685 cm-1 for the structure I and 1715 cm-1 for structure II?



◦ Compound I lacks conjugation, which is present in compound II.
◦ The expected stretching absorption is lowered in all molecules with cyclohexane rings.
◦ Having fewer double bonds results in lowering of all of the stretching absorptions.
◦ The C to O double bond of compound I has greater single bond character than the C to O double bond of compound II.
◦ Compound II has a C to O double bond with considerable single bond character, lowering the expected stretching absorption.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
