Answer to your first question is given below:
 
The haloalkanes and haloarenes can be distinguished by the following tests:
Silver nitrate test:
In this test , the halide is warmed with aqueous  or alcoholic  KOH.
The solution is then acidified with dil.HNO3 and AgNO3 is added.
If precipitate occurs, it indicated alkyl,benxyl or allyl halides.
If precipitate does not occur , it indicates aryl or vinyl halides.
It should be noted that ppt. formed should be soluble in dil.HNO3.
