4. As the energy gap between the HOMO and LUMO orbitals of a molecule decreases, the molecules' electronic absorption spectrum (UV-vis spectrum) will have a larger Amax (lamba max) value. If compound X has a Amax = 388 nm, and compound Y has a max = 442 nm, which compound has more extensive conjugation? Place the name of the compound in the box below.

13C NMR spectroscopy provides valuable information about the environments of a molecule's carbon atoms. 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.
Draw what you expect the 1H spectra of the four compounds to be.

Q 1(a) Methane, CH4 is a tetrahedral molecule and does not exhibit a permanent dipole moment (i.e. it has a dipole moment of 0). Nonetheless, in microwave spectroscopy methane does exhibit a weak, but measurable absorbance. Explain why you think this is the case?
