Electronic Effects
The effect of electrons that are located in the chemical bonds within the atoms of the molecule is termed an electronic effect. The electronic effect is also explained as the effect through which the reactivity of the compound in one portion is controlle…
Drawing Resonance Forms
In organic chemistry, resonance may be a mental exercise that illustrates the delocalization of electrons inside molecules within the valence bond theory of octet bonding. It entails creating several Lewis structures that, when combined, reflect the mole…
Using Molecular Structure To Predict Equilibrium
Equilibrium does not always imply an equal presence of reactants and products. This signifies that the reaction reaches a point when reactant and product quantities remain constant as the rate of forward and backward reaction is the same. Molecular struc…

Chapter 27, Problem 27.23P
Interpretation Introduction

(a)

Interpretation: The product formed from Claisen rearrangement of given starting material is to be predicted.

Concept introduction: Claisen rearrangement is a thermal [3,3] sigmatropic rearrangement. This rearrangement takes place in allyl vinyl ether to form γ,δ-carbonyl compound.

Sigmatropic rearrangements are pericyclic reactions which takes place by concerted mechanism. In these rearrangements migration of sigma bond takes place.
