Протяните руку ! надо! ch3-c(ch3)=ch2+,>

А---(HCl)---C4H9Cl (вторичное хлорпроизводное)---(Na, t)->..---(Br2, hv)-->---(KOH, spirt, t )--> ---(Br2, CCl4)--->?

2(CH3-CH(Cl)-CH2-CH3)---(2Na, t)--->CH3-CH2-CH(CH3)-CH(CH3)-CH2-CH3+2NaCl

CH3-CH2-CH(CH3)-CH(CH3)-CH2-CH3---(Br2, hv)-->CH3-CH2-C(Br)(CH3)-CH(CH3)-CH2-CH3+HBr

CH3-CH2-C(Br)(CH3)-CH(CH3)-CH2-CH3(KOH, spirt, t)--->CH3-CH2-C(CH3)=C(CH3)-CH2-CH3+KBr+H20

CH3-CH2-C(CH3)=C(CH3)-CH2-CH3(Br2, CCl4)-->CH3-CH2-C(Br)(CH3)=C(Br)(CH3)-CH2-CH3

A(Hcl)--C4H9Cl
CH3-CH2-CH2-CH3+HCl>CH3-CH(Cl)-CH2-CH3+H2

CH3-C(CH3)=CH2---(KMnO4, H2SO4, t)-->CH3-C(CH3)=O+CO2+MnSO4+K2SO4+H2O
