Question

Based on the spectrums and acids provided, which acid is being shown by the spectrum? Melting Point was between 101.8-103.5 but i + 10 and - 10 to get a broader range so the Melting Point range is now 91.8-113.5

1.2261 8.0654 8.0382 1.1965 7.3573 3309 2.5064 2.0000 0.1240 0.1083- 14 12 10 8 0 t0om to o raise lbase linewth 10 0 ppm

Answer 1

'H NMR Spectrum Analysis (A) i d: 2.50 ppm (s, 3H, HC) 8: 7.34 ppm (d, 2H, HB). 8: 8.05 ppm (d, 2H, HA) d: 210.80 ppm (ws, 1H, HD) (B) MD) H3CA) (C) The analysis of the data are consistent with the following structure: OH Нас 4-methylbenzoic acid
