NEET levelSingle correct optionDifficulty 1 of 3o2066

Ethene reacts with HBr (i) in the absence and (ii) in the presence of a peroxide. The product in both cases is

  1. A1,1-dibromoethane

  4. Dbromoethane

Answer: D

Ethene is symmetrical, so both ends of the double bond are equivalent and there is no regiochemical choice under either ionic or radical conditions. Both give .
