The major product of the following chemical reaction is:

(CH3)2CH−CH=CH2+HBr→(C6H5CO)2O2 ?\mathrm{(CH_3)_2CH{-}CH{=}CH_2 + HBr \xrightarrow{(C_6H_5CO)_2O_2}\ ?}

  1. A.(CH3)2CH−CH2−CH2−Br\mathrm{(CH_3)_2CH{-}CH_2{-}CH_2{-}Br}✓
  2. B.(CH3)2CH−CH2−CH2−O−COC6H5\mathrm{(CH_3)_2CH{-}CH_2{-}CH_2{-}O{-}COC_6H_5}
  3. C.(CH3)2CH−CH(Br)−CH3\mathrm{(CH_3)_2CH{-}CH(Br){-}CH_3}
  4. D.(CH3)2C(Br)−CH2−CH3\mathrm{(CH_3)_2C(Br){-}CH_2{-}CH_3}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
