Question
What is the right answer and why?
**Question:**

Which of the following alkanes has the highest boiling point?

**Options:**

- 2,3-dimethylpentane
- 2-methylhexane
- heptane
- 3-methylhexane

**Explanation:**

In this multiple-choice question, the student is asked to identify which alkane has the highest boiling point. The options are a list of alkanes with different structural configurations, and the correct option is indicated by the selection of "2,3-dimethylpentane."

**Concept:**

The boiling point of alkanes is influenced by factors such as molecular weight, surface area, and branching. In general, straight-chain alkanes have higher boiling points than their branched counterparts. Therefore, understanding the molecular structure is crucial for predicting boiling points.
