Arrange the following according to liquification pressure (n-pentane, iso-pentane, neo-pentane)

Explanation

To solve the problem of arranging n-pentane, iso-pentane, and neo-pentane according to their liquefaction pressure, we can follow these steps:

### Step 1: Understand the Structures
First, we need to identify the structures of the three compounds:
- **n-pentane**: A straight-chain alkane with the formula CH3-CH2-CH2-CH2-CH3.
- **iso-pentane**: A branched alkane with the formula CH3-CH(CH3)-CH2-CH3, which has one branch.
- **neo-pentane**: A more branched alkane with the formula (CH3)4C, having two branches.
