Chapter 6.11, Problem 19PTS

Interpretation Introduction

Interpretation:

Determined the migratory group and curved arrow pattern of migratory carbocation rearrangement should be identified for the given molecule.

Concept introduction:

Carbocation: carbon atom bears positive charged species with three bonds is called Carbocation and it plays vital intermediate in organic synthesis. Carbocation migratory aptitude is mainly depends on the stability of the carbocation. This type of carbocation undergoes inter or intra molecule reactions and it form more stable product this type of rearrangement called carbocation rearrangement.

Carbocation’s are classified in to three types as primary, secondary and tertiary depending on the number of carbon atoms which is attached to the ionized carbon.

Tertiary carbocation is more stable than secondary carbocation, secondary carbocation is more stable than the primary carbocation as shown below.

Migratory aptitude is the relative ability of a migrating group to migrate in a rearrangement reaction.
