Question

When 2-methylpropane is treated with bromine in the presence of UV light, one product predominates a. Identify the structure of the major productb. Identify the structure of the minor productc. Draw a mechanism for formation of the major product (include all steps:initiation, propagation, and termination)

Answer 1

Answer: Inittiation: Br2 -> Br. + Br.

Propagation: CH3CH(CH3)CH3+Br. -> CH3CH(CH3)CH2. +HBr

CH3CH(CH3)CH2. + Br. -> CH3CH(CH3)CH2Br

CH3CH(CH3)CH2Br +Br. -> CH3C.(CH3)CH2Br +HBr

CH3C.(CH3)CH2Br + Br. -> CH3CBr(CH3)CH2Br

Termination: Br. + Br. ->Br2
