Question

How do I label the NMR's for Vanillyl Alcohol?

H NMR (400 MHz, CDC) Varillyl Aol 13000 9000 ·6000 131 ft (opm) 3C NMR (101 MHz, CDCI) Vandlyl lcohol 26000 24000 22000 18000 12000 4000 2000 230 220 210 200 190 180 170 160 150 140 130 120 1101009080706050 3020100-10 fl (ppm)

Answer 1

In proton nmr at 1.6ppm this is benzylic alcohol O-H proton. Then at 3.9ppm it is OMe methyl 3proton. Then at 4.6ppm there is benzylic CH2 proton and at 5.63ppm this is phenolic OH proton which is ortho to OMe group.and remaining 3 aromatic proton are in 6.8ppm similarly at carbon nmr 55ppm and 66ppm will be OMe methyl carbon and CH2OH benzylic carbon respectively. And other 6 peaks for 6 aromatic carbon.
