написать уравнения реакций превращений: CH₃-CH=CH₂--->(+X₁) CH₃-CH₂-CH₃--->(+X₂) CH₃-CH-CH₃--->(+X₃)--->(Br под CH) | Br --->CH₃-CH-CH-CH₃--->(+X₄) CO₂ (CH₃ под 2 и 3) | | CH₃ CH₃
1)CH3-CH=CH2+H2=CH3-CH2-CH3
2)CH3-CH2-CH3+2Br=(t,hV(свет)) CH3-CH(Br)-CH3+HBr
3)2CH3-CH(Br)-CH3+2Na=CH3-CH(CH3)-CH(CH3)-CH3+2NaBr
4)2C6H14+19O2=12CO2+14H2O
