The major product formed in the following reaction sequence is CH 3 CH = CH 2   → iii   CH 3 CH 2 CHO iv   CrO 3 i   HBr ,   peroxide ii   Mg

Options

  1. A3 - Hexanone
  2. B2 - Hexanone
  3. C2 - Methyl - 3 - pentanone
  4. DHexanal

Correct answer

A. 3 - Hexanone

Step-by-step solution

Propene undergoes anti-markonikov's addtion with HBr in presence of peroxide to from 1-bromopropane. 1-bromopropane reacts with magnesium in presence of dry ether to form the grignard reagent propylmagnesium bromide. Propanal undergoes nucleophilic addition with propylmagnesium bromide to form hexan-3-ol which on oxidation with CrO 3 froms hexan-3-one
