Химия: 50 ! цепочка по органической не разбираюсь. ch3-ch3+cl2→x1+na→x2→ch3-ch=ch-ch3+hcl→x3+naoh→x4+h2→бутан

dhdhhd55 · Answer

1. CH3 - CH3 + Cl2 =(на свету)= CH3 - CH2 - Cl + HCl
2. 2CH3 - CH2 - Cl + 2Na =(t)= CH3 - CH2 - CH2 - CH3 + 2NaCl
3. CH3 - CH2 - CH2 - CH3 =(Ni, t)= CH3 - CH = CH - CH3 + H2
4. CH3 - CH = CH - CH3 + HCl = CH3 - CH2 - CH - CH3
Cl |
| Cl
5.CH3 - CH2 - CH - CH3 + NaOH =(спирт. р-р, t)= CH3 - CH = CH - CH3 + NaCl + H2O
6. CH3 - CH = CH - CH3 + H2 =(Pt, t)= CH3 - CH2 - CH2 - CH3
