Question

PLSSS HELP!!

In the molecule above, the black balls represent carbon atoms and the turquoise balls represent hydrogen atoms. What is the name of this hydrocarbon?

A. trimethylpentane
B. 2-methyl-3-methyl-4-methylpentane
C. 2,2-dimethyl-3-methylpentane
D. 2,3,4-trimethylpentane

Answer 1

D. 2,3,4-trimethylpentane

Answer 2

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
