Answer:
b. 3-methyl hexane
Step-by-step explanation:
To determine the name of a branched chain hydrocarbon, we can follow this steps:
- Identify the longest main chain. In this case, the main chain has 6 carbon atoms (that's why this is a hexane).
- Identify branches, and place them in the lowest position. In this case, the branch is a methyl and it is located in carbon number 3.
Finally, the name is written by placing first the position and type of lateral branch, and at the end the name of the main chain.
So, the name of this compound is 3-methyl hexane.
