Answer

Step by step solution

01

Step-by-Step SolutionsStep 1: Activation energy

The energy barrier between the reactants and the products of a reaction is termed the activation energy i.e., it is the energy to be overcome by the reactants to turn into products.

02

Change in enthalpy (∆H°)

The energy difference between the products and the reactants of a reaction yields the change in enthalpy of the reaction.

03

Energy diagram

The plot of energy vs the reaction coordinate for a reaction gives the energy profile diagram of a chemical reaction.

As we learned in Chapter 4, monosubstituted cyclohexanes exist as an equilibrium mixture of two conformations having either an axial or equatorial substituent. When R=CH2CH3, Keqfor this process is 23. When R=C(CH3)3,Keqfor this process is 4000.

a. When , which conformation is present in higher concentration?

b. Which R shows the higher percentage of equatorial conformation at equilibrium?

c. Which R shows the higher percentage of axial conformation at equilibrium?

d. For which R is more negative?

e. How is the size of R related to the amount of axial and equatorial conformations at equilibrium?

Draw the products of homolysis or heterolysis of each indicated bond. Use electronegativity differences to decide on the location of charges in the heterolysis reaction. Classify each carbon reactive intermediate as a radical, carbocation, or carbanion.

a.

b.

Explain why HC鈮�CHis more acidic than CH3CH3, even though the C-H bond in HC鈮�CHhas a higher bond dissociation energy than the C-H bond in CH3CH3.

Compound A can be converted to either B or C. The energy diagrams for both processes are drawn on the graph below.

  1. Label each reaction as endothermic or exothermic.
  2. Which reaction is faster?
  3. Which reaction generates the product lower in energy?
  4. Which points on the graphs correspond to transition states?
  5. Label the energy of activation for each reaction.
  6. Label the 鈭�H掳 for each reaction.

Although Keqof Equation [1] in Problem 6.57 does not greatly favor formation of the product, it is sometimes possible to use Le Ch芒telier鈥檚 principle to increase the yield of ethyl acetate. Le Ch芒telier鈥檚 principle states that if an equilibrium is disturbed, a system will react to counteract this disturbance. How can Le Ch芒telier鈥檚 principle be used to drive the equilibrium to increase the yield of ethyl acetate? Another example of Le Ch芒telier鈥檚 principle is given in Section 9.8
