CH₃-CH(C₂H₅)-CH₂-CH₂-COOH
CH₃-C(CH₃)₂-COOH
zadanie 2
a)
HCHO + Ag₂O --> HCOOH + 2Ag
HCOOH + NaOH --> HCOONa + H₂O
b)
CH₃CHO + 2Cu(OH)₂ --> CH₃COOH + Cu₂O + 2H₂O
2CH₃COOH + Mg --> (CH₃COO)₂Mg + H₂
c)
CH₃COONa + HCl --> CH₃COOH + NaCl
CH₃COOH + C₂H₅OH --> CH₃COOC₂H₅ + H₂O
d)
CH₃OH + CuO --> HCHO + Cu + H₂O
HCHO + Ag₂O --> HCOOH + 2Ag
HCOOH + CH₃OH --> HCOOCH₃ + H₂O
e)
CH₃CHO + Ag₂O --> CH₃COOH + 2Ag
CH₃COOH + C₆H₅OH --> CH₃COOC₆H₅ + H₂O
f)
C₁₅H₃₁COOC₂H₅ + H₂O --> C₁₅H₃₁COOH + C₂H₅OH

kwas propanowy-C3H6O2
kwas 2 metylopropanowy-CH3CH(CH3)COOH
kwas pentanowy-C5H10O2
a)
CH4 + HCl--> CH3Cl + H2OCH3Cl + H2O --> CH3OH + HCl
CH3OH + H2O --> HCOOH +H2O b)CH3CHO + 2 Cu(OH)2 = CH3COOH + Cu2O + 2 H2O
2 CH3COOH + Mg = (CH3COO)2Mg + H2
c)
CH3COONa+ H2O--->CH3COOH+NaOH CH3COOH+C2H5OH ---> CH3COOC2CH5 + H2Od)
CH3OH + CuO---->HCHO + Cu + H2O
HCHO + Ag2O---->HCOOH + 2Ag
HCOOH + CH3OH--stęż H2SO4--->HCOOCH3 + H2O
HCOOCH3 + NaOH---->HCOONa + CH3OH
e)1. C2H5OH (enzym/odwadnianie) +1/2O2 = CH3CHO + H2O
2. CH3CHO + ½O2 → CH3COOH lub CH3CH2CHO + Ag2O → CH3CH2COOH + 2Ag↓
3. CH3COOH + C2H5OH = CH3COOC2H5 + H2O
f)C15H31COOH + C2H5OH --- H2SO4ŕ--> C15H31COOC2H5 + H2O
C15H31COOC2H5 + H2O ------> C15H31COOH + C2H5OH
C15H31COOH + CH2(OH)-CH(OH)-CH2(OH) ---->(C15H31)3COOC3H5
