Ambiguity in naming haloalkanes

My question in quite simple why a compound such as chloro-ethane is called as such why is if not chloro-ethyl??


Since it is a hydrogen short.




Chloroethane is ethane with 1 hydrogen replaced by chlorine. So it is substituted ethane.


$$\ce{CH3-CH2Cl}$$


1-Chloroethyl or 2-Chloroethyl is **ethyl** with 1 hydrogen replaced by chlorine. So it is substituted ethyl radical, standalone or bound to a larger molecular structure.


$$\ce{CH3-CHCl.}$$


or


$$\ce{CH2Cl-CH2.}$$
