Sharedes · Answer

1. CH3-CH=CH-CH2-CH3 + K2Cr2O7 + H2O = CH3CH(OH)CH(OH)CH2CH3 + KOH + Cr(OH)3
2. CH3-CH=CH-CH2-CH3 + K2Cr2O7 + H2SO4 = CH3COOH + C2H5COOH + Cr2(SO4)3 + K2SO4 + H2O
3. CH3-CH=CH-CH2-CH3 + K2Cr2O7 + KOH = CH3COOK + C2H5COOK + H2O + K3[Cr(OH)6]
4. CH3-CH=C(CH3)-CH2-CH3 + K2Cr2O7 + H2SO4 = CH3COOH + CH3C(O)CH2CH3 + K2SO4 + Cr2(SO4)3 + H2O
5. CH3-CН=CН-CH=CH2 + KMnO4 + H2SO4 = CH3COOH + CO2 + K2SO4 + MnSO4 + H2O
