Write the condensed structural formula of 2,2,4-trimethylpentane.

I was thinking that this might be the answer:
CH_3 C(CH_3)_2 CH_2 CH(CH_3) CH_3

the symbol "_#" represents subscripts

but it's not...

PLEASE HELP!!!

CH3C(CH3)2CH2CH(CH3)2

To write the condensed structural formula of 2,2,4-trimethylpentane, you need to determine the connectivity of the atoms and the number of carbon and hydrogen atoms in each molecule.

First, let's start by understanding the name of the compound. "2,2,4" indicates the positions of the three methyl groups (CH3) on the parent chain, which is pentane (5 carbon atoms). "Trimethyl" specifies that there are three methyl groups attached to the parent chain.

Next, we need to determine the connectivity of the atoms. Begin with the five carbon atoms in a straight chain:

CH3 – CH2 – CH2 – CH2 – CH3

Next, we place the methyl groups at the specified positions. In this case, two methyl groups are attached to the second carbon atom (C2) and one methyl group is attached to the fourth carbon atom (C4). We represent the methyl groups as substituents by using brackets: (CH3).

Following these instructions, the condensed structural formula of 2,2,4-trimethylpentane would be:

CH3 – C(CH3)2 – CH2 – C(CH3) – CH3
