Câu trả lời tốt nhất
a.
CH3CHO + HCN —> CH3-CHOH-CN
CH3-CHOH-CN + 2H2O —> CH3-CHOH-COOH + NH3
CH3-CHOH-COOH —> CH2=CH-COOH + H2O
nCH2=CH-COOH —> (-CH2-CH(COOH)-)n
b.
CH3COCH3 + HCN —> CH3-C(OH)(CN)-CH3
CH3-C(OH)(CN)-CH3 + 2H2O —> CH3-C(OH)(COOH)-CH3 + NH3
CH3-C(OH)(COOH)-CH3 —> CH2=C(CH3)-COOH + H2O
nCH2=C(CH3)-COOH —> (-CH2-C(CH3)(COOH)-)n
