Question


lastly propose a strucutre for compound E

Compound F has a molecular formula of CgHgO. What is the Unsaturation Number (UN) or Double-Bond Equivalent (DBE)? Examine the IR spectrum provided for Compound F. Based on the molecular formula, the UN/DBE you calculated, and the IR spectrum, check all the functional groups that are possibly present in compound F? Examine the 13C and 1H spectra of Compound F. All the proton signals are above 6 ppm. What fragment would account for that and the UN/DBE that you calculated earlier? The singlet at 9.7 ppm is characteristic of which functional group? (spelling counts!) The two doublets at 7.75 and 6.65 ppm are characteristic of which functional group?

Explanation / Answer

ring, benzene ring, ald, ket, alkene, alkyne
