Final answer:
To draw 2,2,4-trimethylpentane, begin with a five-carbon pentane chain, add two methyl groups to the second carbon, and one methyl group to the fourth carbon, completing the structure by adding hydrogen atoms to fulfill the four bonds for each carbon.
Step-by-step explanation:
To draw 2,2,4-trimethylpentane, you should start with the pentane chain, which is a chain of five carbon atoms. Then, add a methyl group (CH3) to the second and fourth carbon atoms. Since there are two methyl groups on the second carbon, you need to draw two branches from that carbon.
Each branch will represent a methyl group. Remember that each carbon atom must have four bonds, so you will complete the structure by adding hydrogen atoms to ensure that. The final structure should have a total of eight carbon atoms because of the three methyl groups added to the base pentane structure.
