PHENYL 2-HYDROXYBENZOATE......COCK WILL TEACH YOU NMR




PHENYL 2-HYDROXYBENZOATE, PHENYL SALICYLATE

 COCK WILL TEACH YOU NMR

Formula: C13H10O3

IR spectrum NMR spectrum

C13H10O3
Rule 2, omit O, gives C13H10
13 - 10/2 + 1 = 9 degrees of unsaturation.
Look for 2 aromatic rings plus another pi bond or aliphatic ring.
The band at 1682 indicates a carbonyl, probably an ester. The band at 3192 indicates C-H aromatic stretch; aromatics also show bands in the regions 1600-1585 and 1500-1400 (C-C in-ring stretch), and 900-675 (C-H out-of-plane). The wide band just to the left of the 3192 band indicates O-H stretch (alcohols and phenols).

Structure answer This is the structure. See if you can assign the peaks on your own.
