2CH3-CH2Cl+2Na=2NaCl+C4H10
CH3-CH2-CH2-CH3+ Br2=CH3-CHBr-CH2=CH3+HBr
CH3-CHBr-CH2-CH3+ NaOH= CH3-CH=CH-CH3+NaCl+H2O
CH3-CH=CH-CH3+HOH= CH3-CH2-CHOH-CH3.
2CH3-CH2Cl+2Na=2NaCl+C4H10
CH3-CH2-CH2-CH3+ Br2=CH3-CHBr-CH2=CH3+HBr
CH3-CHBr-CH2-CH3+ NaOH= CH3-CH=CH-CH3+NaCl+H2O
CH3-CH=CH-CH3+HOH= CH3-CH2-CHOH-CH3.
2) CH3-CH2CL+ KOH(водный)> CH3-CH2OH+KCL
3) C2H5OH+CuO---> CH3-COH+ Cu+ H2O (нагревание)
4) СH3COH+ Ag2O---> CH3COOH+ 2Ag (над стрелкой: NH3, H2O)
