10.2 Reactions of the alkanes
At 2:38, CH3Cl is called chloromethane, not chloroethane.
Understandings:
Alkanes have low reactivity and undergo free-radical substitution reactions.
Applications and skills:
Writing equations for the complete and incomplete combustion of hydrocarbons.
Explanation of the reaction of methane and ethane with halogens in terms of a free-radical substitution mechanism involving photochemical homolytic fission.
Guidance:
Reference should be made to initiation, propagation and termination steps in free-radical substitution reactions. Free radicals should be represented by a single dot.
