1) CH₃-CH(CH₃)-CH₂-CH₃ + Br₂ --> CH₃-CBr(CH₃)-CH₂-CH₃ + HBr
2) 2CH₃-CH₂-Br + 2Na --> CH₃-CH₂-CH₂-CH₃ + 2NaBr
3) CH₃-CH₂-CH₂-COONa + NaOH --> CH₃-CH₂-CH₃ + Na₂CO₃
4) CH₃-CH₂-CH=CH₂ + HBr --> CH₃-CH₂-CH₂Br-CH₃
5) CH₂=CH-NO₂ + HBr --> CH₃-CHBr-NO₂
6) CH₂=CH-CH=CH₂ + Br₂ --> CH₂Br-CHBr-CH=CH₂ + Br₂ -->
-->CH₂Br-CHBr-CHBr-CH₂Br
7) CH₃-C(CH₃)=CH-CH₂-CH₃ + 3[O] ---> CH₃-CH₂-COOH +
CH₃-C(O)-CH₃
8) CH₃-CH=CH₂ + Cl₂ --> CH₃-CHCl-CH₂Cl
