2.---> CH3-CH2-CH2Br
------>CH3-CH(CH3)-CHBr-CH2Br
---------> CH3-CCl2-CCl2-CH3
-----> C6H5-CH2-CH2Cl+HCl
------> CH3-CH(CH3) CH2Br+HBr-
----> CH3-C(CH3)Cl-CH2Cl
3. a)CH2=CH-CH3 +Br2---> CH2=CH-CH2Br +HB
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 +HBr---> CH3-CBr2-CH3
d)CH2=CH-CH3+ Br2---> CH2=CH-CH2Br+HBr
CH2=CH-CH2Br+HBr--> CH3-CHBr-CH2Br
