5. Compound $$\mathrm{X}$$ has a molecular formula of $${\mathrm{C}}_7{\mathrm{H}}_{16}$$. In $$13\mathrm{C}$$ NMR, compound I gave 3 peaks and in 1H NMR it also gave 3 peaks, a doublet, a triplet and a multiplet. Provide a structure for compound I. (1 point) 6. Deduce the identity of the following compound from the $$1\mathrm{H}\mathrm{NMR}$$ data given. $${\mathrm{C}}_8{\mathrm{H}}_{10}\mathrm{O}:?$$ $$3.4(3\mathrm{H}$$, singlet), $$4.5(2\mathrm{H}$$, singlet $$),7.2(5\mathrm{H},\mathrm{m})$$ (ppm) (1 point) 7. How many $$13\mathrm{C}$$-signals are possible for the following molecules? (1 point)
