Identify the correct set of reagents or reaction conditions ' (X ) ' and ' (Y ) ' in the following set of transformation

Options

  1. A( X = ) dil.aq. ( NaOH , 20^ C , Y = Br ₂ / CHCl ₃ )
  2. B( X = ) conc.alc. ( NaOH , 80^ C , Y = Br ₂ / CHCl ₃ )
  3. C( X = ) dil.aq. ( NaOH , 20^ C , Y = HBr ) /acetic acid
  4. D( X = ) conc.alc. ( NaOH , 80^ C , Y = HBr / ) acetic acid

Correct answer

D. ( X = ) conc.alc. ( NaOH , 80^ C , Y = HBr / ) acetic acid

Step-by-step solution

CH ₃- CH ₂- CH ₂- Br X = conc.alc. NaOH CH ₃- CH = CH ₂ Y HBr / Acetic acid CH ₃- CHBr - CH ₃
