Question

102. Adiția hidrogenului, clorului, HCl și apei la 1-butenă.

Answer 1

CH2=CH-CH2-CH3+  Cl2 →CH2-CH-CH2-CH3

                                              │       │

                                             Cl       Cl

 

 

CH2=CH-CH2-CH3 + HCl→ CH3-CH-CH2-CH3 -conform Markovnicov

                                                       │

                                                      Cl

CH2=CH-CH2-CH3 +H2→ CH3-CH2-CH2-CH3 –REACTIA ARE LOC IN PREZENTA DE Ni

Adica pui pe sageata Ni

CH2=CH-CH2-CH3 +H-OH → CH3-CH-CH2-CH3 -conform Markovnicov-

                                                         │

                                                        OH

 

PE SAGEATA PUI H2SO4 NU RAMANE AICI

Answer 2

H2C=CH-CH2-CH3 + Cl2 ⇒ H2CCl-CHCl-CH2-CH3
                                    + HCl ⇒ H3C-CHCl-CH2-CH3
                                    + HOH ⇒ H3C-CH(OH)-CH2-CH3
