Odpowiedź:
1. COOH - grupa karboksylowa
2. P, F, F, P, P, F, P,
3. a) HCOOH m= 46u %C≈ 26%
b) C3H7COOH m= 88u %C≈ 54,5%
4. HCOOH--> HCOO- +H+ - ( kation wodoru i anion metanianowy)
2 CHCOOH +K --> 2 CH3COOK +H2 - octan (etanian) potasu
C2H5COOH+ Li2O --> C2H5COOLi +H2O - propionian (propanian) litu
C3H7COOH+Ca(OH)2--> C3H7COOCa +H2O - maślan (butanian) wapnia
jonowy: C3H7COO - + H+ + Ca+ + 2OH- --> C3H7COO - + H+ +H2O
skrócony jonowy: H+ + OH- ---> H2O
