|
CH3

2) X1 + KOH =>X2
3) X2 + HBr => X1
4) X1 + Na => X3
5) X3 => CO2

Answer 1

Ответ:

Объяснение:

1) H₃C-CH₂-CH(CH₃)-CH₃ + Br₂ =(hv)=> H₃C-CH₂-C(Br)(CH₃)-CH₃ (X1) + HBr;

2) H₃C-CH₂-C(Br)(CH₃)-CH₃ + KOH (вод. р-р) => H₃C-CH₂-C(OH)(CH₃)-CH₃ (X2) + KBr;

3) H₃C-CH₂-C(OH)(CH₃)-CH₃ + HBr => H₃C-CH₂-C(Br)(CH₃)-CH₃ (X1) + H₂O;

4) H₃C-CH₂-C(Br)(CH₃)-CH₃ + 2Na => H₃C-CH₂-C(CH₃)₂-C(CH₃)₂-CH₂-CH₃ (X3) + 2NaBr;

5) 2H₃C-CH₂-C(CH₃)₂-C(CH₃)₂-CH₂-CH₃ + 31O₂ => 20CO₂ + 22H₂O.
