Question

I am having difficulty identifying the proton locations from the H NMR for methyl diantilis. Any help is appreciated thank you!

Answer 1

In this strutture there are eight proton HNMR peoks are there each have different PPM chemical shift. In the first proton as of above numbered only one single peak , because there is no adjacent proton and it is the election donating group and it is shifted to the upfield due to the increased electron density so that the this proton obtain in the 5.36PPM 2 In the second proton also attached to the electron donating group and it is 2H , and also attached to the adjacent there. proton so it is (n+1) peak of quadret peat obtain at 4.02 PPM ③ In the third proton it is attached to the two adjacent proton of so it is 34 of the driplet peaks obtain at 1.32 PPM In the fourth proton it is not attached to the any other Proton, so it will give the 14 of singlet peat at 6.87 PPM © In the fifth proton is attached to the election donating group and did not attached to any adjacent proton so it will give the 24 d singlet at 4.80 POM 16 In the sixth proton is also attached to the electron donating group and did not attacked to the any adjacent carbon so it will give me 34 of singlet at 3.30 PPM ② In the seventha proton of the Bengene ring uit will to I give the H o double because it is attached to the another linproton of Benzene ring so it will give 6.480PM . In the eight proton, of the Benzene ring give the 14 a doublet because it is attached to the another single Proton of Bengene eing it is just away from the electron donating group so it will give the 14 of of double to at 6. 77 ppay 0 0
