Here's why:

* Alkane: The main carbon chain (CH3-CH2-CH2) is a straight chain of three carbon atoms with only single bonds, making it an alkane.

* Halide: The "Cl" at the end represents a chlorine atom, which is a halogen. When a halogen atom is attached to an alkane, it forms a haloalkane.

Therefore, the specific name for this compound is 1-chloropropane.
