1. C2H5NH2COOH + HCl = NH3ClC2H5COOH
2. 2NH2CH2COOH + 2Na = 2NH2CH2COONa + H2
3. NH2C3H7COOH + C2H5OH (t>140°,h2so4(k))= NH2C3H7COOC2H5 + H2O
4. NH2CH2COOH + NH2C2H5COOH = NH2CH2CONHC2H5COOH + H2O
5. NH2C2H5COOH + KOH = NH2C2H5COOK + H2O
6. 1) C6H6 + OHNO2(k) (h2so4(k))= C6H5NO2 + H2O
2) C6H5NO2 + 3H2 (kat)= C6H5NH2 + 2H2O
3) C6H5NH2 + 3Br2 = C6H2Br3NH2 + 3HBr
7. 1) C2H5OH + CuO (t)= CH3COH + Cu + H2O
2) CH3COH + Ag2O (t,NH3*H2O)= CH3COOH + 2Ag
3) CH3COOH + Cl2 ((CH3COO)3Co)= CH2ClCOOH + HCl
4) CH2ClCOOH + 2NH3 = CH2NH2COOH + NH4Cl
8. C6H5NH2 + OHNO2 (k)= C6H4NH2NO2 + H2O
9. C6H5NH2 + HCl = [C6H5NH3]Cl
n(C6H6) = m/M = 156 г / 78 г/моль = 2 моль
n(C6H5NO2) = n(C6H6) — по уравнению
n(C6H5NO2) = 2 моль
m(C6H5NO2) теоретическая = nM = 2 моль * 123 г/моль = 246 г
ω выхода = m практическая / m практическая * 100% = 220 г / 246 г * 100% = 89,34%
ответ: ω выход = 89,34%
