6) Which of these spectra contains an alkyne? Explain the reasoning behind your choice and circle the peak(s) that are associated with the alkyne. 100 D 100 4000 4500 1000 2008 2000 HAVENUBR AVENUMBERI 1000 1000 jmm 1900 1000 380 100
Part A Draw C4HgBr₂ that has the following ¹H NMR spectrum: 1.97 (s, 3H), 3.89 (s, 1H). Hint: Draw C4H₁0 (there are two isomers), and then replace two H atoms with Br atoms. NOTE NOTE! C4H8Br2 has 8 H's! But the integral is 3H and 1H!!! How will you fix that? Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. H 12D EXP L CONT 1
