Question

Scrieti ecuatiile reactiilor chimice urmatoare:
a) Halogenarea alilica a propenei
b)oxidarea blanda a 2-butena
c)aditia HCl la propena
d)clorura fotochimica a metanului

Answer 1

a) CH2=CH-CH3 + H2 => CH3-CH2-CH3

b) CH3-CH=CH-CH3 + K2Cr2O7 + H2SO4 => 2CH3-CH=O + K2SO4 + Cr2(SO4)3 + H2O

c) CH3-CH=CH2 + HCl => CH3-CH(Cl)-CH3        [regula lui Markovnikov]

d) CH4 + Cl2 => CH3Cl + HCl

CH4 + 2Cl2 => CH2Cl2 + 2HCl

CH4 + 3Cl2 => CHCl3 + 3HCl

CH4 + 4Cl2 => CCl4 + 4HCl
