Помогите решить кр по химии

1)CH3-CH2-COOH + CH3-CH2-CH2-CH2-OH ←→ CH3-CH2-COOCH2-CH2-CH2-CH3 + H2O

2)CH3-COOH + CH3-(CH2)4-CH2OH ←→ CH3-COO-(CH2)5-CH3 + H2O

3)CH3-(CH2)6-COOH + CH3-CH2-CH2-CH2OH ←→ CH3-(CH2)6-COO-(CH2)3-CH3 + H2O



3
CaC2 + 2H2O → Ca(OH)2 + C2H2
C2H2 + H2 →Ni,t,p→ C2H4
C2H4 + H2O →H3PO4,t,p→ C2H5OH
CH3-CH2-CH2-CH2-COOH + C2H5OH → ←C4H9-COOC2H5 + H2O
