Why isn't the name of the compound:
3-ethyl-2,2-dimethylheptane?

I started numbering from the top (which gives a main chain length of 7 carbons). I started from the top because it would maximize the number of substituents in the name which I thought was a rule.

The book's answer is 3-tert-butylheptane which has less substituents in the name.

Yup you're right. 3-tert-butylheptane is the best answer choice though. I searched around for an answer and it looks like this was discussed not so long ago on a different thread lol http://forums.studentdoctor.net/showthread.php?t=831358

Alright thanks for the help! I thought maybe my knowledge of the IUPAC rules was incorrect.
