H3C-CH2-CH2-CH(он нег внизу) -CH2-CH(от него внизу)-CH2-CH3

                         \CH3                                   \C2H5        

Answer 2

To write the chemical formula for 6-ethyl-4-methyloctane, we first need to understand the structure of the molecule. The name "6-ethyl-4-methyloctane" tells us that it is an alkane (a hydrocarbon with single bonds) with a chain of 8 carbon atoms. The "6-ethyl" part means there is an ethyl group (C2H5) attached to the 6th carbon atom, and the "4-methyl" part means there is a methyl group (CH3) attached to the 4th carbon atom.

The main chain of the alkane contains 8 carbon atoms, and the ethyl group is attached to the 6th carbon, while the methyl group is attached to the 4th carbon. Here's the structural representation:

         CH2-CH3

The chemical formula of 6-ethyl-4-methyloctane is: C10H22

Explanation: The main chain of the alkane contains 8 carbon atoms (C8H18), and we add one ethyl group (C2H5) to the 6th carbon and one methyl group (CH3) to the 4th carbon. This results in a total of 10 carbon atoms and 22 hydrogen atoms.
