1) (CH3)2C=CH-CH=CH-CH3 + Br2 → (CH3)2CBr-CH=CH-CHBr-CH3
(CH3)2C=CH-CH=CH-CH3 + Br2 → (CH3)2CBr-CHBr-CH=CH-CH3
(CH3)2C=CH-CH=CH-CH3 + Br2 → (CH3)2C=CH-CHBr-CHBr-CH3
2) CH3-CH2-CH=CH-CH=CHBr + Br2 → CH3-CH2-CHBr-CH=CH-CHBr2
CH3-CH2-CH=CH-CH=CHBr + Br2 → CH3-CH2-CHBr-CHBr-CH=CHBr
CH3-CH2-CH=CH-CH=CHBr + Br2 → CH3-CH2-CH=CH-CHBr-CHBr2
