******LINE A IS DEPT 90, LINE B IS DEPT 135******

Problem 2. Deduce the structure of the molecule with formula c10Huo using the 300 MHz H NMR, DaF-cosY, HETCOR and 75 MHz 13C and DEPT NMR Spectra multiplicities.) Assign all signals in the spectra by writing directly on the traces. (Label Include a table that correlates the data obtained in the different experiments. Map your structure showing the coupled hydrogens with labels. Box your final structure with labels to match the signals in the spectra. from 2D Briefly explain assignments in terms of chemical shift, coupling and correlations experiments 760 720 1170 1130 1940 1900 1570 1530 460 420 400 360 300 260 680 640 560 520 ppm

Explanation / Answer

1 HNMR spectra indicates that from 1-2 ppm - R3C-H alkyl and R-ch2-R ,R-C=O (CH3) may there. 4-7 PPM , 5-5.3 R2C=CHR,phenol may be there.

According to dept it gives the clearaity in 13C NMR - 4 inverted peaks indicates that 4 CH2 groups are present. and CH3 and CH peak appears normal.

CH2 - 60 ppm , 45 ppm -CH , 25 PPM -CH3

CH2=CH CH2 CH2 CH2 O CH2CH2 CH2 CH=CH2
