Interpretation Introduction

Interpretation:

An energy diagram for the addition of HBr to 1-pentene is to be drawn. Both the curves, one for the formation of 1-bromopentane and another for the formation of 2-bromopentane, are to be shown in the same diagram indicating the positions of all the reactants, intermediates and products.The curve which has the higher-energy carbocation intermediate and that which has the higher-energy first transition state are to be identified.

Concept introduction:

The carbocation II is more stable than I. Hence it is easily formed, has less energy and its formation will be more exergonic.
