For each reaction, give the reagent and the solvent used in reaction 1, reaction 2 and reaction 3.
If 1-iodobutane, $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{I}$, is used under the same conditions as reaction 1, butan-1-ol is produced. How, if at all, would the rate compare with the reaction of 1-bromobutane? Refer to suitable Data Booklet information in your explanation.
State two properties of CFCs that made them suitable as aerosol propellants.
When CFCs are present in the upper atmosphere, homolytic fission takes place in the presence of ultraviolet light. What is meant by the term homolytic fission?
Suggest an equation for the homolytic fission of $\text{CCl}_2\text{F}_2$.
The most common replacements for CFCs as aerosol propellants are hydrocarbons such as propane and butane. Suggest one disadvantage of these compounds as aerosol propellants.
