b.The formation of diacetone alcohol:

c.

Short Answer

Answer

(a)鈭�S0is positive(鈭�S0鈮�0).

(b) 鈭�S0is negative.(鈭�S0鈮�0)

(c) 鈭�S0cannot be predicted.

Step by step solution

01

Step 1: Entropy

Entropy may be defined as a measure of randomness, disorder,or freedom of motion.Two smaller molecules (or fragments, such as radicals) have more freedom of motion (greater entropy) than one larger molecule.

Reactions tend to favor products with the greatest entropy. A positive value of entropy change鈭�S0 implies that the products have more freedom of motion than the reactants.

02

Predicting the sign of∆S0

(a) In this reaction, products have more freedom of motion. So,鈭�S0has a positive value.

(b) In this reaction, reactants have more freedom of motion. So,鈭�S0has a negative value.

(c) The value of 鈭�S0cannot be predicted for this reaction.

(a) Draw the reaction-energy diagram for the following reverse reaction:

(b) What is the activation energy for this reverse reaction?

(c) What is the heat of reaction (螖 H0 )for this reverse reaction?

When exactly 1 mole of methane is mixed with exactly 1 mole of chlorine and light is shone on the mixture, a chlorination reaction occurs. The products are found to contain substantial amounts of di-, tri-, and tetrachloromethane, as well as unreacted methane.

(a) Explain how a mixture is formed from this stoichiometric mixture of reactants, and propose mechanisms for the formation of these compounds from chloromethane.

(b) How would you run this reaction to get a good conversion of methane toCH3Cl? Of methane to CCl4?

(a) Draw the structure of the transition state for the second propagation step in the chlorination of methane.

Show whether the transition state is product-like or reactant-like and which of the two partial bonds is stronger.

(b) Repeat for the second propagation step in the bromination of methane.

Question: Under base-catalyzed conditions, two molecules of acetone can condense to form diacetone alcohol. At room temperature250c, aboutof 5%the acetone is converted to diacetone alcohol. Determine the value of鈭�G0for this reaction.

The chlorination of pentane gives a mixture of three monochlorinated products.

(a) Draw their structures.

(b) Predict the ratios in which these monochlorination products will be formed, remembering that a chlorine atom abstracts a secondary hydrogen about 4.5 times as fast as it abstracts a primary hydrogen.
