Textbook Question
Chapter 11, Problem 68IAE
A conjugated hydrocarbon has an alternation of double and single bonds. Draw the molecular orbitals of the p system of 1,3,5- hexatriene. If the energy required to excite an electron from the HOMO to the LUMO corresponds to a wavelength of 256 nm, do you expect the wavelength for
the corresponding excitation in 1,3,5,7-octatetraene to be a longer or shorter wavelength? [Hint: Refer to Figure 11-34.]

An electron in the 7 orbital of ethylene (C,H,) is excited
by a photon to the * orbital. Do you expect the equilib-
rium bond length in the excited ethene molecule to be
greater or less than that in ground-state ethene? Will the
vibrational frequency in the excited state be higher or
lower than in the ground state? Explain your reasoning.
6) This question is concerned with vibrational spectra (Infrared and Raman).
a) How many normal modes of vibration are expected in these molecules? (Show calculations)
i) Theobromine (the caffeine-like stimulant that is found in chocolate)
b) In the molecular vibration shown here for trans-1,4-dichlorocyclohexane, both
chlorine atoms stretch away from the carbon to which they are bonded
(arrows). Will this mode be IR active?
Will this mode be Raman active?
In each case, why or why not?
ii) Cyanopolyyne (an organic molecular wire that has been detected spectroscopically in interstellar space, and
is postulated to be a precursor to biomolecules: HC=C-C=C-C=N
c) Why are CH4 and CO₂ considered greenhouse gases, but O₂ and N₂ are not?
d) Are the vibrations shown here a degenerate pair (Yes/No)?
Why or why not?

- β-Carotene (1) is a linear polyene in which 10 sing le and 11 double bonds alternate along a chain of 22 carbon atoms. If the length of each CC bond is taken to be about 140 pm , then the length L of the molecular box in β-carotene is L = 2.94 nm.

Calculate the rotational constant (in J) for the diatomic in part a. Using your value for the rotational constant in part b, determine the energy of the transition from state 3 to state 4 (in J). Do you expect the energy of the transition from state 3 to state 4 for 2H19F to be larger or smaller than what you computed in part c, assuming that the bond length does not change? Explain your choice based on the relevant equations, or calculate the energy for this transition. Steps 1, 2 and 3 have already been found. I need help with the last question only but I haven't been able to get it solved since there can only be three questions answered.

- The infrared absorbtion of the N-H stretch in amines occurs approximately at a wavelength of 2.9 x 10-6 m. What is the approximate vibrational force constant, k, of N-H bond?

For example, a carbon–carbon bond in a linear polyene may have bonding character in the HOMO and antibonding character in the LUMO. Therefore, promotion of an electron from the HOMO to the LUMO weakens this carbon–carbon bond in the excited electronic state, relative to the ground electronic state. Consult Figs. 9E.2 and 9E.4 and discuss in detail any changes in bond order that accompany the π*←π ultraviolet absorptions in butadiene and benzene.arrow_forwardCalculate the wavelength pf light that is absorbed when a n electron in the molecule CH2=CH-CH=CH-CH=CH-CH=CH-CH=CH2 is promoted from the HOMO to the LUMO.

Since carbon atoms are often connected to hydrogen atoms, which could split the carbon signal through spin-spin coupling, the coupling between C and H is often "turned off" through the use of broadband decoupling, causing each C signal to appear as a singlet. Draw an isomer of C5H11Cl that would be expected to have four resonances in its 13C NMR spectra.arrow_forward
