(b) How does the conjugation of carbonyl group to carbon-carbon double bond affect the stretching frequency of carbonyl group?

                   

3. (a) Give the definition and approximate range (in wavenumbers) of:

                   

(a1) Diagnostic region

                   

(a2) Fingerprint region

                   

(b) Explain why it is unreliable to draw a conclusion about the presence of certain functional groups, based solely on the signals from the fingerprint region.

Calculate the absorption frequency corresponding to the –C-H stretching vibration treating the group as a simple diatomic C-H molecule with a force constant of k= 5.0 102 N/m. (Hint: use the actual mass of the two atoms to determine the reduced mass. Note that N is the unit of a force.) Repeat the calculation for the deuterated bond.
