Question

Here is the NMR spectrum of cyclohexene. We were unable to use the synthesized cyclohexene because it was mixed with water, it gave two layers when put in the NMR tube. So this cyclohexene came from a bottle. Assign all the peaks to the protons in cyclohexene.

Answer 1

(1 ppm) H2 H2 (0.5 ppr X H1 (~5 ppm) Hy TĪ H₂ H 1 (~5ppm) H1 protons will appear at mont downfield region due to attached with more electronegative sp² - c atoms. H2 protons will appear at more downfield region than H3 protons because H2 protons are nearer to sp² e atoms.
