Text Solution

AI Generated Solution

To arrange n-hexane, 3-methylpentane, and 2,2-dimethylbutane in the increasing order of their boiling points, we need to consider the effect of molecular structure, specifically branching, on boiling points. ### Step-by-Step Solution: 1. **Understanding the Structures**: - **n-Hexane**: This is a straight-chain alkane with six carbon atoms (C6H14). Its structure is: ``` CH3-CH2-CH2-CH2-CH2-CH3 ...
