Answer 2

It seems like you are trying to provide the name of a chemical compound using a nomenclature system that specifies the number and positions of substituents on a hydrocarbon chain. However, there seems to be a typo in your input. The correct name for the compound should be "2-ethyl-4-methyl-2-hexene."

Now, let's convert this name into a chemical formula. The molecular formula of the compound is C9H18. It consists of 9 carbon atoms and 18 hydrogen atoms.
