a) 2CH3-CH2-CH2OH + 2Na → 2CH3-CH2-CH2ONa + H2↑
2CH3-CH(OH)-CH3 + 2Na → 2CH3CHONaCH3 + H2
b) CH3-CH2-CH2OH + CuO ----to→ CH3-CH2-CHO + Cu + H2O
CH3-CH(OH)-CH3 + CuO ----to→ CH3COCH3 + Cu + H2O
c) CH3-CH2-CH2OH + HBr → CH3-CH2-CH2Br + H2O
CH3-CH(OH)-CH3 + HBr → CH3CHBrCH3 + H2O
d) CH3OH + CH3-CH2OH → CH3CO2CH3 + 2H2
3CH3OH + CH3-CH(OH)-CH3 → 2CH3CO2CH3 + 4H2
