IUPAC NAME for CH3CH2C(CH3)2CH(CH2CH3)CH3

Click For Summary The IUPAC name for CH3CH2C(CH3)2CH(CH2CH3)CH3 is 2-ethyl-3,3-dimethylpentane, not 3-methyl-4,4-dimethylhexane. The confusion arises from the longest carbon chain identification; the structure contains five carbons, making it a pentane rather than a hexane. The correct naming prioritizes the longest chain and the position of substituents. The discussion highlights the importance of accurately determining the longest carbon chain in organic compounds. Understanding these naming conventions is crucial for correct IUPAC nomenclature. aatari Messages 73 Reaction score 3 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?

mfb Mentor Insights Author Messages 37,398 Reaction score 14,233 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. Last edited: Jan 21, 2019
