Identify the most suitable reagents (I) and (II) for the following sequence of reactions

Options

  1. A( I )= conc. H ₂ SO ₄,( II )= HBr
  2. B( I )= aq. KOH ,( II )= HBr / peroxide
  3. C( I )= alc. KOH ,( II )= HBr / peroxide
  4. D( I )= alc. KOH ,( II )= HBr

Correct answer

D. ( I )= alc. KOH ,( II )= HBr

Step-by-step solution

When 1-bromopropane react with alcoholic KOH , it will form prop-1-ene (X) . Alcoholic KOH is used to give elimination reaction. In next step, HBr (II) is used to give Markownikoff's addition to the alkene and produces 2-bromopropane.
