Questions & Answers

Q: How do you determine the longest carbon structure in a compound?

To determine the longest carbon structure, you look for the chain or ring with the most carbons. In this case, the cyclooctane ring has the most carbons.

Q: What is the prefix used for a four-carbon ring?

The prefix used for a four-carbon ring is "but-". Therefore, the cyclobutyl groups in the compound are named as cyclobutyl.

Q: How do you determine the numbering of the groups in the compound?

The numbering of the groups is determined by the alphabetical order of the prefixes. Cyclobutyl takes precedence over cyclopropyl, so it is numbered first. Similarly, isobutyl is numbered after cyclobutyl.

Q: What is the systematic name for the compound?

The systematic name for the compound is 1,6-dicyclobutyl-7-cyclopropyl-2,4-bis(2-methylpropyl)cyclooctane.

Summary & Key Takeaways

  • The longest carbon structure in the provided compound is a cyclooctane with eight carbons in a cycle.

  • There are two cyclobutyl groups in the compound, both with four carbons in a ring.

  • There is a cyclopropyl group with three carbons in a ring.

  • There are two isobutyl groups, each with four carbons in a Y shape.
