Chapter 6, Problem 46 a
Using cyclohexane as one of your starting materials, show how you would synthesize the following compounds.
(a) 
Verified step by step guidance1
Step 1: Begin with cyclohexane as the starting material. Cyclohexane is a saturated hydrocarbon with the molecular formula C6H12.
Step 2: To introduce a bromine atom onto the cyclohexane ring, perform a free radical halogenation reaction. This reaction typically requires the presence of bromine (Br2) and a source of UV light or heat to initiate the formation of bromine radicals.
Step 3: The bromine radicals generated will abstract a hydrogen atom from cyclohexane, forming a cyclohexyl radical. This radical will then react with another bromine molecule to form bromocyclohexane.
Step 4: Ensure that the reaction conditions are controlled to favor monobromination rather than polybromination. Excess bromine or prolonged reaction times can lead to multiple bromine atoms being added to the cyclohexane ring.
Step 5: Isolate and purify the bromocyclohexane product using techniques such as distillation or recrystallization, depending on the physical properties of the compound.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Free Radical Halogenation
Free radical halogenation is a reaction where alkanes react with halogens (like bromine) in the presence of heat or light to form alkyl halides. The process involves the generation of free radicals, which are highly reactive species with unpaired electrons. In the case of cyclohexane, bromine can abstract a hydrogen atom, leading to the formation of bromocyclohexane.

Cyclohexane Structure
Cyclohexane is a six-membered carbon ring with the molecular formula C6H12. It is a saturated hydrocarbon, meaning it contains only single bonds between carbon atoms. The structure allows for various conformations, such as chair and boat forms, which influence its reactivity and interactions with other reagents during chemical reactions.

Reaction Mechanism
Understanding the reaction mechanism is crucial for predicting the products of organic reactions. In free radical halogenation, the mechanism consists of three steps: initiation (formation of radicals), propagation (reaction of radicals with the substrate), and termination (recombination of radicals). Each step is essential for understanding how cyclohexane can be transformed into bromocyclohexane.

Textbook Question
Strawberry growers have used large quantities of methyl bromide (b.p. 4 °C) to sterilize the soil before planting their crops. Like some of the freons, methyl bromide can diffuse up into the stratosphere, where it damages the protective ozone layer. Agricultural chemists have suggested using methyl iodide (b.p. 43 °C) as a replacement for methyl bromide. Why is methyl iodide likely to be more toxic to agricultural pests (and people) than methyl bromide? Why is methyl iodide less likely to reach the stratosphere than methyl bromide?
