Roughly re-draw the 1H−NMR spectrum on your answer sheet. This suggests the possibility of various functional groups, primarily containing a carbonyl group or an alcohol. The mass spectrum shows two molecular ions with m/z of 136 and 138, and the base peak at m/z = 57. And the number of sites of unsaturation. 0 H0. Note that the compound has 6 carbons but only 4 signals! Determine the structure of the compound based on its molecular formula and its 13C NMR spectrum. C 6 H 12 O IR: nothing interesting 7 - The spectrum displayed is a "decoupled" 13-C NMR spectrum. 19. This suggests that the molecule contains an alcohol functional group. (IHD) IHD= C + 1 + N/2 - H/2 - X/2. In this post we’re going to go through four (simple) practice problems where you’ll be Provides H NMR data for Beginning Problem 12. 0 likely has an ester functional group.
