а) C Na
2CH3-CH(CH3)-CH2-CH2-OH +2 Na -> 2CH3-CH(CH3)-CH2-CH2-ONa + H2
2CH3-CH(OH)-CH2-COH + 2Na = 2CH3-CH(ONa)-CH2-COH + H2
2CH3-CH2-CH2-COOH + 2Na ->2 CH3-CH2-CH2-COONa + H2
2C6H5OH + 2Na -> 2C6H5ONa + H2
C6H3(OH)(CH2-CH2OH) -> C6H3(ONa)(CH2-CH2-ONa) + H2
б) c NaOH
CH3-CH(CH3)-CH2-CH2-OH + NaOH -> CH3-CH(CH3)-CH2-CH2-ONa + H2O
CH3- CH(OH)-CH2-COH + NaOH -> CH3-CH(ONa)-CH2-COH + H2O
CH3-CH2-CH2-COOH + NaOH -> CH3-CH2-CH2-COONa + H2O
C6H5OH + NaOH -> C6H5ONa + H2O
C6H3(OH)(CH2-CH2-OH) + NaOH -> C6H3(ONa)(CH2-CH2-ONa) + 2H2O

Ответ:
Fe(OH)₃ → x1→х2 → FeS → x3 →x4 Fe(OH)₃
2Fe(OH)₃=Fe₂O₃+3H₂O
Fe₂O₃+3H₂=2Fe+3H₂O
Fe+S=FeS
FeS+H₂SO₄=FeSO₄+H₂S
FeSO₄+2NaOH=Na₂SO₄+Fe(OH)₂↓
4Fe(OH)₂ + O₂ +2H₂O = 4Fe(OH)₃↓
