Major product of the given has to be predicted. Also reason for why the pathway creates the predominant product is favorable has to beexplained. Concept Introduction: Carbonyl compound when treated with LDA (Lithium Diisopropylamide) undergoes deprotonation at the α -carbon to form enolate. The enolate formed is resonance stabilized as the negative charge will be spread over other atoms too. The resonance stabilized intermediate undergoes reaction with other molecule of carbonyl (same or different) to form the respective products. If LDA is used as a base the less substituted α carbon is deprotonated due to steric hindrance. Deprotonation of α carbon to form enolate Nucleophilic attack of enolate S N 2 reaction with alkyl halide Racemic mixture: A racemic mixture is simply a mixture containing an equal amount of each enantiomer. Asymmetric center is a sterocenters which arises to hydrocarbons if the carbon is bonded to four different groups.

For the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.
