What is the correct name for 2,4-diethyl-4-ethoxyhexane? A classmate asks you to draw the structure of 2,4-diethyl-4-ethoxyhexane, which he cannot find in a chemical reference manual. Draw the structure of 2,4-diethyl-4-ethoxyhexane.









  (Question continued...) The reason your classmate cannot find the compound in a chemical reference manual is that 2,4-diethyl-4-ethoxyhexane is the incorrect name for the compound. What is the correct name?




Here are my steps:


I count the longest carbon chain = 7 carbons = -heptane
I look at all the substituents: 1 ethoxy group, 1 ethyl group and 1 methyl group
I number the carbon chain starting from the end closer to the ethoxy group (alphabetical order)
I add all the substituents and the carbon chain together




In this case, this is the name I come up with: 3-ethoxy-3-ethyl-5-methylheptane, which is incorrect. Can somebody tell me where I went wrong, please?
In short, your answer is correct. The steps that you have taken are correct, so it's likely the online homework tool has a key mistake.
