Cum se rezolva schema?

Answer 1

a)
CH3-CH2-I -(dehidrohalogenare)-> CH2=CH2 + HI
CH2=CH2 + Br2 -> BrCH2-CH2Br
CH2Br-CH2Br + 2KCN -> NC-CH2-CH2-CN + 2KBr
b)
CH3-CH=CH-CH3 + HCl -> CH3-CH2-CH(Cl)-CH3
CH3-CH2-CH(Cl)-CH3 + Mg -(eter)-> CH3-CH2-CH(MgCl)-CH3
CH3-CH2-CH(MgCl)-CH3 + H2O -> CH3-CH2-CH2-CH3 + MgCl(OH)
c)
3CH3-CH2-CH2-OH + PCl3 -> 3CH3-CH2-CH2-Cl + P(OH)3
CH3-CH2-CH2-Cl -> CH3-CH=CH2 + HCl
CH2=CH-CH3 + HBr -> CH3-CH(Br)-CH3
CH3-CH(Br)-CH3 + H2O -(HO-)-> CH3-CH(OH)-CH3 + HBr
d)
CH3-C≡C-CH3 + H2 -(Pd/Pb2+)-> CH3-CH=CH-CH2
CH3-CH=CH-CH3 + Br2 -> CH3-CH(Br)-CH(Br)-CH3
CH3-CH(Br)-CH(Br)-CH3 + 2H2O -(HO-)-> CH3-CH(OH)-CH(OH)-CH3 + 2HBr
e)
3HO-(CH2)3-OH + 2PCl3 -> 3Cl-(CH2)3-Cl + 2P(OH)3
Cl-(CH2)3-Cl + Zn -> ciclopropan + ZnCl
