Question

Н-С4Н10 --t, Kat--> X1 --> 1,4 –дибромбутен-2--NaOH(водн)-> X2—KMnO4, H2SO4--> X3—Na--> X4. Помогите

Answer 1

CH3-CH2-CH2-CH3 -> CH2=CH-CH=CH2 +2H2
 CH2=CH-CH=CH2 +Br2 -> CH2Br-CH=CH-CH2Br 
CH2Br-CH=CH-CH2Br + 2NaOH -> CH2OH-CH=CH-CH2OH + 2NaBr
5OH-CH2-CH=CH-CH2-OH+16KMnO4+24H2SO4=5HOOC-COOH+16MnSO4+8K2SO4+34H2O
HOOC-COOH+2Na=NaOOC-COONa+H2↑
