Answer:
The correct answer is option D. 2,3,4-trimethylpentane
Step-by-step explanation:
Hello! Let's solve this!
In the drawing we see as the main chain, the longest, one of five carbon atoms. Then we would name it pentane.
Furthermore we see that in carbons 2, 3 and 4 it has a methyl.
So it's trimethyl.
Therefore the name that we form is 2,3 and 4 trimethyl-pentane.
We conclude that the correct answer is option D. 2,3,4-trimethylpentane
