Химическая цепочка
1) CH3-CH2-CH-CH3 + Br2(свет) => X1
|
CH3

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

Answer 1

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

5) H3C-CH2-C(CH3)2-C(CH3)2-CH2-CH3 + 15.5O2 = 10CO2 + 11H2O.
