Correct the following incorrect names using standard IUPAC nomenclature. [Draw a compound that corresponds to the incorrect name, and then rename it.]
(c) 6-ethyl-3-methyloctane

검증된 단계별 안내

Step 1: Begin by drawing the structure of the compound based on the incorrect name '6-ethyl-3-methyloctane'. Start with an octane backbone (a chain of 8 carbon atoms) and add substituents: an ethyl group (-CH₂CH₃) at carbon 6 and a methyl group (-CH₃) at carbon 3.

Step 2: Analyze the structure to determine if the substituents are correctly numbered according to IUPAC rules. The longest continuous chain should be identified, and the substituents should be numbered to give the lowest possible locants.

Step 3: Check if the numbering of the substituents can be improved. If the substituents are not numbered correctly (i.e., the lowest locants are not assigned), renumber the chain starting from the end that gives the substituents the smallest possible numbers.

Step 4: Rename the compound based on the corrected numbering. List the substituents in alphabetical order, followed by the parent chain name. Ensure that the locants are correctly assigned and separated by hyphens.

Step 5: Verify the corrected name by ensuring it adheres to all IUPAC nomenclature rules, including proper placement of substituents, correct numbering, and alphabetical order.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

IUPAC Nomenclature

IUPAC nomenclature is a systematic method for naming organic chemical compounds. It provides rules for identifying the structure of a compound based on its name, ensuring that each compound has a unique and universally accepted name. Understanding these rules is essential for correctly interpreting and renaming compounds, as it involves identifying the longest carbon chain, substituents, and their positions.

Alkane Structure

Alkanes are saturated hydrocarbons consisting only of carbon and hydrogen atoms, connected by single bonds. Their general formula is CnH2n+2, where 'n' is the number of carbon atoms. Recognizing the structure of alkanes is crucial for determining the correct naming conventions, as it helps in identifying the longest carbon chain and the placement of substituents.

Substituent Naming and Positioning

Substituents are groups of atoms that replace hydrogen atoms in a hydrocarbon chain. In IUPAC nomenclature, substituents are named and numbered based on their position on the main carbon chain. Correctly identifying and naming substituents, as well as their positions, is vital for accurately renaming compounds, as it affects the overall name and structure of the molecule.
