[DonLemon]

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
