Expert Answer:

Halohydrocarbons are divided into two types:
1) Haloalkane: (No aromatic ring only alkanes)
2) Haloarenes: [both alkane (as a substituent) and aromatic rings]
 
Therefore, while naming for haloalkanes/alkenes/alkynes, alkane should be the parent name whereas for haloarenes or substituted haloarenes the parent name will be arenes.
 
Hence, the iupac name of m-ClCH2C6H4CH2C(CH3)3 is 1-chloromethyl-3-(2,2-dimethylpropyl) benzene.
