Final Answer:
The root name for a hydrocarbon with eight carbon atoms is "octane." The prefix and side group names depend on specific substituents or branches, requiring additional information for precise identification.
Step-by-step explanation:
The root name of a hydrocarbon, which is a compound consisting only of carbon and hydrogen atoms, is determined by the number of carbon atoms in the longest continuous chain. In your case, with eight carbon atoms, the root name would be "octane." Octane belongs to the alkane family, which consists of saturated hydrocarbons with single bonds between carbon atoms.
The prefix in organic chemistry provides information about any substituent groups or branches attached to the main carbon chain. For example, if there are side groups or substituents in your molecule, they will be named using prefixes such as "methyl," "ethyl," or "propyl" based on the number of carbon atoms in the side group. If there are no substituents, the prefix is simply omitted.
As for the side group name, without specific information about the substituents attached to the eight-carbon chain, I can't provide a precise side group name. Side groups can vary, and their names are determined by the specific functional groups or alkyl groups present.
In summary, for a hydrocarbon with eight carbon atoms, the root name is "octane." The prefix will depend on any side groups or substituents present, and the side group name will be determined by the nature of these substituents. To provide a more accurate answer, additional details about the specific structure of the molecule, including any side groups or functional groups, would be necessary.
