Which isomer of `C_(4)H_(9)Cl` will have the lowest boiling point?

Explanation

To determine which isomer of C₄H₉Cl has the lowest boiling point, we need to follow these steps:

### Step 1: Identify the Isomers of C₄H₉Cl
C₄H₉Cl can have several structural isomers. The possible isomers include:
1. 1-Chlorobutane (CH₃-CH₂-CH₂-CH₂Cl)
2. 2-Chlorobutane (CH₃-CH₂-CHCl-CH₃)
3. 1-Chloro-2-methylpropane (CH₃-CH(CH₃)-CH₂Cl)
4. 2-Chloro-2-methylpropane (CH₃-C(CH₃)(Cl)-CH₃)
