Chapter 8, Problem 101P

Interpretation Introduction

Interpretation: The faster reaction should be determined using the reaction coordinate diagram.

Concept introduction:

• Reaction coordinate diagram is an abstract one dimensional coordinate which represents progress along a reaction pathway.
• The mathematical relationship between enthalpy (H) and free energy (G) is,

  ${\text{ΔG}}^{\text{0}}\text{=}{\text{ΔH}}^{\text{0}}\text{-}\text{TΔS}$

• Reactant: These are the substances initially present in a chemical reaction. 
• Product: These are the substances produced from reactants after a successful reaction.
• Transition state: It is a hypothetical state that occurs in the space between the reactant and products in a chemical reaction.
• Intermediate: It is a molecular entity formed from the reactants and reacts further to give the products.
  • More stable reactant forms the more stable carbocation intermediate.
• Conjugated double bonded compounds are always more stable than the compounds having isolated double bonds.
