Answer 1

Answer #1

Methyl salicylate is also called methyl 2-hydroxy benzoate. The structure is as follows.

3-9 ppm COOCH3 10-7 ppmm

As shown in the figure above, , the proton belongs to –OH appears at 10.7 ppm and the proton belongs to –COOCH3 appears at 3.9 ppm in the HNMR spectrum of methylsalicylate.
