Vedclass · Answer

(A) $1$. Identify the longest carbon chain: The longest continuous chain contains $7$ carbon atoms, so the parent alkane is heptane.$2$. Numbering the chain: Number the chain from the end that gives the substituents the lowest possible locants. Numbering from left to right gives substituents at positions $3$ and $5$. Numbering from right to left also gives substituents at positions $3$ and $5$.$3$. Alphabetical order: When locants are the same from both ends, the substituent that comes first alphabetically gets the lower number. Ethyl $(E)$ comes before methyl $(M)$. Therefore, the ethyl group is assigned position $3$ and the methyl group is assigned position $5$.$4$. Final Name: $3$-ethyl-$5$-methylheptane.
