is (a and a) the figure below (C any compound that is shown in a ~ D 9 H 11 NO 2 of) 1 H-NMR spectrum is (300MHz). 1700 cm IR spectrum at (neat) compounds exhibit a Zua -1 in the vicinity, also, compounds that exhibit a spinal is 1650 cm IR spectrum at (Nujol) -1 shows a strong absorption both in the vicinity. Right combination of compounds and any spectrum. However, I lost signal around 3.4 ppm of Zua, of around 7.9 ppm and 6.3 ppm near the spinal when you heavy water processing. The signal based on the measurement solvent have been removed. a 2-Ethoxybenzamide b 4-Ethoxybenzamide c ethyl 3-Aminobenzoate D ethyl 4-Aminobenzoate
