Example: One of the structures shown is H-C-C-C-C-H, which represents a four-carbon chain with a bromine atom attached. | | | H Br H

Definition: Halogenated alkanes are compounds where one or more hydrogen atoms in an alkane have been replaced by halogen atoms.

Highlight: The position of the halogen atom in the carbon chain is crucial for correct naming.

Example: The compound CH₃-CH₂-CH-CH₂-CH₃ is correctly named as 3-ethylpentane. | CH₂-CH₃

Highlight: Pay attention to the numbering of the carbon chain and the position of substituents when naming branched alkanes.

Vocabulary: Substituents are groups or atoms that replace hydrogen atoms in the parent hydrocarbon chain.

Example: The compound H-C-C-C-H is correctly named as 2-bromopropane. | | H Br

Highlight: In naming halogenated alkanes, the position of the halogen is indicated by a number, and the halogen is treated as a substituent.

Vocabulary: Prefixes such as "chloro-", "bromo-", and "iodo-" are used to indicate the presence of specific halogens in the compound.

Example: One of the structures shown is CH₃-CH₂-CH₂-CH-CH₂-CH₃, which is an example of a branched alkane. | CH₃

Highlight: Understanding the naming conventions for alkanes is crucial as it forms the basis for naming more complex organic compounds.

Vocabulary: Alkanes are saturated hydrocarbons with only single bonds between carbon atoms.
