I) а)C4H10 => CH2=CH-CH=CH2
+ 2H2
б)CH2=CH-CH=CH2 + Br2 =>CH2Br-CHBr –CH=CH2
в)CH2Br-CHBr –CH=CH2
+ 2NaOH (водн.)
=>CH2OH-CHOH-CH=CH2 + 2NaBr
г) 3CH2OH-CHOH-CH=CH2 + 2KMnO4 + 4H2O =>
3CH2OH-CHOH-CHOH-CH2OH
+ 2MnO2 +2 KOH
д) 2CH2OH-CHOH-CHOH-CH2OH + 2Na => 2CH2ONa-CHOH-CHOH-CH2OH
+ H2
II) а)С2H6 + Br2 = C2H5Br + HBr
б) C2H5Br + KOH =C2H5OH + KBr
в) 3C2H5OH + K2Cr2O7 +4 H2SO4 = 3CH3COH + Cr2(SO4)3 + K2SO4 + 7H2O
г) CH3COH +H2 = C2H5OH
д) C2H5OH = C2H4+H2O
