Mechanism for free-radical chlorination of cyclobutane

Step by step solution

01

Free radicals

An atom or group of atoms containing odd or unpaired electron is known as the free radical. The unpaired electron is represented by a single unpaired dot in the formula. Free radicals are electrically neutral. They are highly reactive species formed by homolytic fission of a covalent bond.

02

Steps involved in free radical chain reaction

In a free-radical chain reaction, free radicals are generally created in the initiation steps. A free radical and a reactant is combined to yield a product and another free radical in the propagation steps. Lastly, the number of free radicals generally decrease in the termination steps.

03

Mechanism

The mechanism consists of three parts which are initiation step, propagation step I and propagation step II.

For each compound, predict the major product of free-radical bromination. Remember that bromination is highly selective, and only the most stable radical will be formed.

(a) cyclohexane

(b) methylcyclopentane

(c) decalin

Question: Free-radical chlorination of hexane gives very poor yields of 1 clorohexyane, while cyclohexane can be converted to chlorocyclohexane in good yield.

(a)How do you account for this difference?

(b) What ratio of reactants (cyclohexane and chlorine)

(a) Draw an approximate reaction-energy diagram for the acid-base reaction of phenol (see below) with 1-molar aqueous sodium hydroxide solution.

(b) On the same diagram, draw an approximate reaction-energy diagram for the acid-base reaction oftert- butyl alcohol(see below) with 1-molar aqueous sodium hydroxide solution.

Question: (a) Use bond-dissociation enthalpies from Table 4-2 (page 203), calculate the heat of reaction for each step in the free-radical bromination of methane.

(b) Calculate the overall heat of reaction.
