For the protons labeled Ha and Hb in the structure, predict the characteristics of their signals in the H1 NMR spectrum: the approximate chemical shift, the splitting pattern, and the integration value. A carbon is bonded to two methyl groups and two ethyl groups. The C H 3 protons in the ethyl group are labeled as A and the C H 2 protons in the ethyl group are labeled as b. The approximate chemical shift of Ha is 5 to 6 ppm 1 ppm 3 to 4 ppm 1. 6 ppm 2 ppm 1. 3 ppm The approximate chemical shift of Hb is 1. 3 ppm 3 to 4 ppm 1 ppm 5 to 6 ppm 1. 6 ppm 2 ppm The expected splitting pattern of Ha is quintet quartet doublet multiplet singlet triplet The expected splitting pattern of Hb is doublet multiplet quartet triplet singlet

Ha:Chemicalshift: 1.3 ppm,Splittingpattern: Quartet, Integration: 3.Hb:Chemicalshift: 1.6 ppm,Splittingpattern: Triplet, Integration: 2.We have,ForHa:The approximatechemicalshiftof Ha is 1.3 ppm.The expectedsplittingpatternof Ha is a quartet.The integration value of Ha will depend on the number of protons in the neighboring groups that are chemically equivalent.Since Ha is bonded to two methyl groups (A) in the ethyl group, we can expect an integration value of 3 (quartet).Each methyl group will contribute one proton, so the signal for Ha will be split into four peaks of equal intensity.ForHb:The approximatechemicalshiftof Hb is 1.6 ppm.The expectedsplittingpatternof Hb is a triplet.The integration value of Hb will also depend on the number of protons in the neighboring groups that are chemically equivalent.Since Hb is bonded to two ethyl groups (b) in the molecule, we can expect an integration value of 2 (triplet).Each ethyl group will contribute one proton, so the signal for Hb will be split into three peaks of equal intensity.Thus,Ha:Chemicalshift: 1.3 ppm,Splittingpattern: Quartet, Integration: 3.Hb:Chemicalshift: 1.6 ppm,Splittingpattern: Triplet, Integration: 2.Learn more aboutchemicalshiftshere:brainly.com/question/14468372#SPJ4...
