SUMMARY

The correct IUPAC name for the compound CH3CH2C(CH3)2CH(CH2CH3)CH3 is 2-ethyl-3,3-dimethylpentane. This conclusion is based on identifying the longest carbon chain, which consists of five carbon atoms, confirming it as a pentane rather than a hexane. The confusion arises from the structural interpretation of the substituents, but the naming follows the IUPAC rules for prioritizing the longest chain and the correct placement of substituents.

PREREQUISITES
  • Understanding of IUPAC nomenclature rules
  • Familiarity with organic chemistry structures
  • Knowledge of substituent naming conventions
  • Ability to identify the longest carbon chain in organic compounds

I don't understand why CH3CH2C(CH3)2CH(CH2CH3)CH3 is 2 ethyl-3,3 dimethyl - pentane and not 3-methyl-4,4-dimethylhexane. When I expand the condensed formula above and count the longest carbon chain, it seem it is a hexane rather than pentane. Can someone please clarify?

Homework Statement


Write the IUPAC name for CH3CH2C(CH3)2CH(CH2CH3)CH3.

Homework Equations


none.

The Attempt at a Solution


3-methyl-4,4-dimethylhexane

Unless I misunderstand the CH2CH3 part, you are right with the hexane part:

CH3 - CH2 - C(CH3)2 - CH(CH2CH3) - CH3

Although I would have expected, 3,3,4-trimethyl-hexane. Here it is.
