Question

Exercițiul 3.3 , vă rog!

Answer 1

a.  CH2=CH-CH3+Br2(t)---> CH2=CH-CH2Br+HBr

CH2=CH-CH2Br+Br2---> CH2=CH-CHBr2+HBr

CH2=CH-CHBr2+ H2---> CH3-CH2-CHBr2

b. CH2=CH-CH3 +Br2----> CH2Br -CHBr-Ch3

c.   CH≡C-CH3 +HBr---> CH2=CBr-CH3

     CH2=CBr-CH3+HBr---> CH3-CBr2-CH3

d.  CH2=CH-CH3 +Br2---->CH2=CH-CH2Br

  CH2=CH-CH2Br+HBr---> CH2Br-CH2-CH2Br
