Interpretation:
An energy diagram for a two step reaction in which both steps are exergonic and in which the second step has a higher energy transition state than the first is to be drawn and the parts of the diagram corresponding to reactant, product, intermediate, overall ΔG# and overall ΔG0 are to be labeled.
Concept introduction:
Energy diagrams are used to depict graphically the energy changes that occur during a reaction. The vertical axis of the diagram represents the energy of all the reactants and the horizontal axis, called reaction progress, represents the progress of the reaction from beginning to end. The reactants are shown in left and the products in the right. The transition state represents the highest energy structure involved in the particular step reaction. The overall ΔG# is the energy difference between the reactants and highest transition state and overall ΔG0 is the free energy difference between the reactants and products. Every step in a reaction has a separate energy diagram.
To draw:
An energy diagram for a two step reaction in which both steps are exergonic and in which the second step has a higher energy transition state than the first and further to label the parts of the diagram corresponding to reactant, product, intermediate, overall ΔG# and overall ΔG0.

- SH 0arrow_forward2. Please consider the two all 'cis' isomers of trimethylcyclohexane drawn below. Draw the two chair conformers of each stereoisomer below (1 and 2) and calculate their torsional interaction energies in order to identify the lower energy conformer for each stereoisomer. Based on your calculations, state which of the two stereoisomers 1 and 2 is less stable and which is more stable. [1,3-diaxial CH3 CH3 = 3.7kcal/mol; 1,3-diaxial CH3 H = 0.88kcal/mol; cis-1,2 (axial:equatorial) CH3 CH3 = 0.88kcal/mol; trans-1,2-diequatorial CH3 CH3 = 0.88kcal/mol) all-cis-1,2,3- 1 all-cis-1,2,4- 2arrow_forwardNonearrow_forward

Measurements indicated that 2,250 mg of acetone evaporated. Calculate the acetone concentration in micrograms per cubic meter.arrow_forwardPlease help me answer number 1. 1. If your graphs revealed a mathematical relationship between specific heat and atomic mass, write down an equation for the relationship. I also don't understand, is the equation from the line regression the one that I'm suppose use to show the relationship? If so could you work it all the way out?arrow_forward
- Describe the principle of resonance and give a set of Lewis Structures to illustrate your explanation.arrow_forwardDon't used hand raitingarrow_forwardIt is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect.
