Question

What is the name of this hydrocarbon?

1) 2,3-dimethylpentane
2) 3,4-dimethylbutane
3) 3,4-diethylpentane
4) 2,3-diethylbutane

Answer 1

The name of this hydrocarbon is 2,3-dimethylbutane.

Step-by-step explanation:

The name of this hydrocarbon is 2,3-dimethylbutane. The longest chain has four carbon atoms, making it a butane. There are two substituents, each consisting of a single carbon atom, known as methyl groups. The methyl groups are attached to the second and third carbon atoms in the chain, resulting in the name 2,3-dimethylbutane.
