- A C¬D (carbon–deuterium) bond is electronically much like a C¬H bond, and it has a similar stiffness, measured by the spring constant, k. The deuterium atom has twice the mass (m) of a hydrogen atom, however. A chemist dissolves a sample in deuterochloroform (CDCl3) and then decides to take the IR spectrum and simply evaporates most of the CDCl3. What functional group will appear to be present in this IR spectrum as a result of theCDCl3 impurity?arrow_forwardThe NMR spectrum of bromocyclohexane indicates a low field signal (1H) at δ 4.16. To room temperature, this signal is a singlet, but at -75 ° C it separates into two peaks of unequal area (but totaling one proton): δ 3.97 and δ 4.64, in ratio 4.6: 1.0. How do you explain the doubling in two peaks? According to the generalization of the previous problem, what conformation of the molecule predominates (at -75 ° C)?

- In Section 15.5c, we learned that the frequency of the C=0 stretch for an amide is lower than it is for a ketone, suggesting that the C=0 bond is weaker in an amide. This weakening of the C=0 bond can be explained by the significant contribution from one of its resonance structures toward the resonance hybrid. Draw that resonance structure for N,N-dimethylacetamide [CH3CON(CH3)2] and explain how it accounts for the weakening of the C=0 bond.arrow_forwardFor each organic compound in the table below, enter the locant of the highlighted side chain.
