Chapter 8, Problem 74IP

Interpretation Introduction

Interpretation:

Synthesis path should be drawn for the given transformation with reagents

Concept introduction:

• Reagent: reagent is a compound or compound mixture that is used in the chemical transformation of the reactions. Reagents for some reactions are given below.
  • Elimination reaction: in elimination reaction, two substituents are removed from the substrate to give the product in presence of base.
  • Elimination of compound in presence of bulky base leads to less substituted alkene, in presence of strong base (not bulky) leads to more substituted alkene.
  • Addition reaction: in addition reaction, two substituents are added to the reactant without losing any compound.
  • Hydration: addition of water molecule across the double bond is called hydration reaction. Hydration of alkene can be achieved in many ways.
  • Hydroboration-oxidation reaction: addition of –H and –OH group across the double bond in presence of borane and hydrogen peroxide with base is known as hydroboration-oxidation reaction.
  • Simple hydration in acidic media gives the addition product through carbocation intermediate.
  • Hydro halogenation: hydrogen and halogen added across the double bond of the alkene in Markovnikov’s path is called hydro halogenation. This addition reaction proceeds via anti-Markovnikov’s path in presence of peroxides.
