WHAT IS THE NAME OF THIS SKELETAL FORMULA?

abb0t · Answer

IUPAC rules states that you should name it according to the longest chain. The others are just groups AND in the lowest number possible. 

The longest chain is 7 - hepta
and there are no double or triple bonds, so you can just use the suffix "ane"
and you have a methyl and an ethyl group in positions 2 and 4, respectively.
Now, just put it all together. And you have your name.
